+# AGENTS.md
+
+Repository-specific instructions for coding agents working on `blog-frontend`.
+
+## Project Overview
+
+- This is the frontend for WYPark Blog, built with Next.js 16 App Router, React 19, TypeScript, Tailwind CSS 4, TanStack React Query, Zustand, and Axios.
+- The app talks to a backend API through `NEXT_PUBLIC_API_URL`.
+  - Local default: `http://localhost:8080`
+  - Production API used by deploy: `https://blogserver.wypark.me`
+  - Public site metadata uses: `https://blog.wypark.me`
+- Node 20 is the production baseline. The Docker build uses `node:20-alpine`.
+
+## Repository Layout
+
+- `src/app/`: Next.js App Router routes, root layout, providers, metadata, sitemap, and robots.
+- `src/components/layout/`: persistent layout components such as `Sidebar` and `TopHeader`.
+- `src/components/post/`: post listing, detail, Markdown rendering, search, and TOC components.
+- `src/components/comment/`: comment form, list, and item components.
+- `src/api/`: API client wrappers. Use these instead of calling backend endpoints directly from components.
+- `src/api/http.ts`: shared Axios instance, auth header injection, and token refresh handling.
+- `src/store/authStore.ts`: persisted auth state with Zustand.
+- `src/types/index.ts`: shared API and domain types.
+- `public/`: static assets.
+- `.gitea/workflows/deploy.yml`: Gitea deployment pipeline.
+- `DockerFile`: production Docker image definition. Keep the current filename casing unless changing the deploy workflow too.
+
+## Package Manager And Commands
+
+- Prefer `npm` for scripts and dependency work because `package-lock.json`, Docker, and CI use npm.
+- Do not update both `package-lock.json` and `yarn.lock` for routine changes. If dependencies must change, update the npm lockfile and leave a note about the lockfile decision.
+- Common commands:
+  - `npm ci` to install dependencies from the lockfile.
+  - `npm run dev` to start local development on port 3000.
+  - `npm run lint` for ESLint.
+  - `npm run build` for production build validation.
+  - `npm run start` after a successful build.
+
+## Environment
+
+- Use `NEXT_PUBLIC_API_URL` when testing against a non-local backend.
+- Features that fetch categories, posts, profile, comments, auth, or uploads require the backend API to be reachable.
+- If the backend is not running, prefer validating static rendering, linting, and isolated UI logic instead of inventing mock API behavior.
+
+## Coding Conventions
+
+- Keep TypeScript strict. Add or refine shared types in `src/types/index.ts` instead of spreading untyped `any` through components.
+- Use the `@/*` alias for imports from `src`.
+- Prefer existing local patterns over new abstractions.
+- Keep components focused and colocate small UI-only helpers near the component that uses them.
+- Preserve the existing Tailwind-first styling approach. Use global CSS only for app-wide behavior or third-party component overrides.
+- Prefer icons from the existing icon libraries (`lucide-react`, `@heroicons/react`) instead of custom inline SVGs.
+- User-facing copy is Korean-first. When editing Korean text, save files as UTF-8 and verify the rendered text or diff so strings do not become mojibake.
+- Some existing files contain Korean comments and UI strings. Do not mass-rewrite text while making unrelated changes; fix only the text needed for the task.
+
+## Next.js App Router Rules
+
+- Use Server Components by default.
+- Add `'use client'` only when a component uses hooks, browser APIs, localStorage, React Query hooks, Zustand hooks, events, or client-only libraries.
+- Components that use `useSearchParams` should remain under a `Suspense` boundary.
+- Dynamic route params follow the current Next.js 16 style in this repo, where route components may receive `params` as a `Promise`.
+- Keep metadata, sitemap, and robots changes aligned with the production domain `blog.wypark.me`.
+
+## Data Fetching And API Rules
+
+- Use `src/api/*` functions from UI code. Add new backend calls there before consuming them in components.
+- Use `http` from `src/api/http.ts` for authenticated JSON API calls so auth headers, credentials, and refresh behavior stay consistent.
+- Direct `axios` calls should be limited to token refresh paths or cases where the shared interceptor would recurse.
+- API responses generally follow `ApiResponse<T>` with useful data under `response.data.data`.
+- Keep React Query keys stable and descriptive, following existing patterns such as `['posts', ...]`, `['post', slug]`, `['categories']`, `['profile']`, and `['comments', postSlug]`.
+- After mutations, invalidate or reset the related queries rather than relying on stale cache state.
+
+## Auth And Permissions
+
+- Auth state lives in `useAuthStore` and is persisted under `auth-storage`.
+- Admin-only UI checks generally use `_hasHydrated` plus `role?.includes('ADMIN')`.
+- Avoid reading localStorage during server rendering. Gate browser-only auth logic behind client components and effects.
+- Be careful around token refresh. There is queueing and Web Locks logic in `src/api/http.ts`; do not simplify it without testing concurrent 401 behavior.
+- Do not expose refresh tokens or auth tokens in logs, UI, or error messages.
+
+## Markdown And Content Rendering
+
+- Render post content through `src/components/post/MarkdownRenderer.tsx`.
+- Keep `rehype-sanitize` in the Markdown pipeline unless there is a deliberate, reviewed security change.
+- When adding Markdown features, consider XSS, external links, image behavior, syntax highlighting, TOC generation, and SSR/client compatibility.
+- Uploaded images are inserted as Markdown image syntax by the write page. Preserve that convention unless changing backend upload semantics too.
+
+## UI And UX Guidelines
+
+- Preserve the main layout: fixed sidebar on larger screens, mobile sidebar toggle, top-right auth/write controls, content area with responsive widths.
+- Keep blog reading surfaces calm and content-focused. Avoid large decorative sections unless the user explicitly asks for a redesign.
+- Ensure text fits on mobile and desktop, especially Korean labels in buttons, cards, modals, and sidebar items.
+- For admin flows, keep destructive actions confirmed and visually distinct.
+- For forms, preserve loading, disabled, error, and success states with `react-hot-toast` or the existing local patterns.
+
+## Validation Expectations
+
+- For most code changes, run `npm run lint`.
+- Run `npm run build` when changing routing, layout, metadata, data fetching, auth, Markdown rendering, or build/deploy config.
+- For visible UI changes, start `npm run dev` and verify the affected route in a browser when feasible.
+- If validation cannot run because dependencies or the backend are unavailable, state that clearly and explain what was checked instead.
+
+## Deployment Notes
+
+- The production Docker image uses standalone Next output. Keep `next.config.ts` `output: 'standalone'` unless the deployment strategy changes.
+- The Gitea workflow builds on pushes to `main`, passes `NEXT_PUBLIC_API_URL=https://blogserver.wypark.me`, runs the container as `blog-frontend`, and maps host port `3005` to container port `3000`.
+- Keep Docker, Gitea workflow, and Next config changes synchronized.
+
+## Change Discipline
+
+- Keep edits scoped to the requested task.
+- Record completed work in `LOG.md` as part of each task. Include the date, a brief summary of changes, and any validation performed or skipped.
+- When finishing a task and updating `LOG.md`, also leave a concise note about the recommended next task so future agents can continue smoothly.
+- Do not rewrite generated files, `.next`, `node_modules`, build output, or unrelated lockfiles.
+- Do not silently change public URLs, analytics IDs, SEO behavior, auth storage keys, or backend endpoint paths.
+- When touching fragile areas such as auth refresh, Markdown sanitization, deployment, or route params, include a short explanation and stronger validation.

+## Overview
+
+Apple's web presence is a masterclass in **reverent product photography framed by near-invisible UI**. Every page is a stack of edge-to-edge product "tiles" — alternating light and dark canvases, each centered on a hero headline, a one-line tagline, two tiny blue pill CTAs, and an impossibly crisp product render. Nothing competes with the product. Typography is confident but quiet; color is either pure white, an off-white parchment, or a near-black tile; interactive elements are a single, quiet blue.
+
+Density is unusually low even by contemporary SaaS standards. Each tile occupies roughly one viewport, and there is no decorative chrome — no borders, no gradients, no decorative frames, no shadows on headlines. Elevation appears only when a product image rests on a surface (a single soft `rgba(0, 0, 0, 0.22) 3px 5px 30px` drop for visual weight). The result is a catalog that feels more like a museum gallery: the wall disappears and the artifact takes over.
+
+Store and shop surfaces retain the same chassis but switch modes. The product configurator (iPhone 17 Pro, accessories grid) introduces a tight grid of white utility cards at `{rounded.lg}` (18px) radius with a thin border, paired with a persistent thin sub-nav strip. The environment page leans darker and more editorial. Across all five surfaces the typographic system, spacing rhythm, and the single blue accent are consistent — this is one design language expressed at different volumes.
+
+**Key Characteristics:**
+- Photography-first presentation; UI recedes so the product can speak.
+- Alternating full-bleed tile sections: white/parchment ↔ near-black, with the color change itself acting as the section divider.
+- Single blue accent (`{colors.primary}` — #0066cc) carries every interactive element. No second brand color exists.
+- Two button grammars: tiny blue pill CTAs (`{rounded.pill}`) and compact utility rects (`{rounded.sm}`).
+- SF Pro Display + SF Pro Text — negative letter-spacing at display sizes for the signature "Apple tight" headline feel.
+- Whisper-soft elevation used only when a product image needs to breathe — exactly one drop-shadow in the entire system.
+- Tight two-row nav: slim `{component.global-nav}` + product-specific `{component.sub-nav-frosted}` with persistent right-aligned primary CTA.
+- Section rhythm across multiple pages: light hero → dark product tile → light utility tile → dark tile → parchment footer — a predictable pulse.
+
+## Colors
+
+> **Source pages analyzed:** homepage, environment, store, iPhone 17 Pro buy page, accessories index. The color system is identical across all five surfaces; only the surface-mode mix differs.
+
+### Brand & Accent
+- **Action Blue** (`{colors.primary}` — #0066cc): The single brand-level interactive color. All text links, all blue pill CTAs ("Learn more", "Buy"), and the focus ring root. This is Apple's quiet but universal "click me" signal. Press state shifts to a slightly darker variant via the active scale transform rather than a hex change.
+- **Focus Blue** (`{colors.primary-focus}` — #0071e3): A marginally brighter sibling of Action Blue, reserved for the keyboard focus ring on buttons (`outline: 2px solid`).
+- **Sky Link Blue** (`{colors.primary-on-dark}` — #2997ff): A brighter blue used on dark surfaces for in-copy links and inline callouts, where Action Blue would disappear against the tile background.
+
+### Surface
+- **Pure White** (`{colors.canvas}` — #ffffff): The dominant canvas. Content, utility cards, store tiles, configurator grids.
+- **Parchment** (`{colors.canvas-parchment}` — #f5f5f7): The signature Apple off-white. Used for alternating light tiles, footer region, and the default page canvas in store utility sections. Just different enough from white to create rhythm.
+- **Pearl Button** (`{colors.surface-pearl}` — #fafafc): A near-white used as the fill for secondary "ghost" buttons — lighter than the parchment canvas so the button still reads as a button against `{colors.canvas-parchment}`.
+- **Near-Black Tile 1** (`{colors.surface-tile-1}` — #272729): The primary dark-tile surface on the homepage product grid.
+- **Near-Black Tile 2** (`{colors.surface-tile-2}` — #2a2a2c): A micro-step lighter — used where a dark tile sits directly above or below Tile 1 to create the faintest separation.
+- **Near-Black Tile 3** (`{colors.surface-tile-3}` — #252527): A micro-step darker — used at the bottom of the stack and in embedded video/player frames.
+- **Pure Black** (`{colors.surface-black}` — #000000): Reserved for true void — video player backgrounds, edge-to-edge photographic overlays, the global nav bar background.
+- **Translucent Chip Gray** (`{colors.surface-chip-translucent}` — #d2d2d7): The base hex of the translucent gray chip used over photography for circular control buttons. In production, applied at ~64% alpha as `rgba(210, 210, 215, 0.64)`.
+
+### Text
+- **Near-Black Ink** (`{colors.ink}` — #1d1d1f): The voice of every headline, every body paragraph, and the dark utility button's fill. Chosen instead of pure black to keep the page feeling photographic rather than printed.
+- **Body** (`{colors.body}` — #1d1d1f): Same hex as ink — Apple uses one near-black tone for all text on light surfaces.
+- **Body On Dark** (`{colors.body-on-dark}` — #ffffff): All text on dark tiles and on the global nav bar.
+- **Body Muted** (`{colors.body-muted}` — #cccccc): Secondary copy on dark tiles where pure white would be too loud.
+- **Ink Muted 80** (`{colors.ink-muted-80}` — #333333): Body text on the white Pearl Button surface — slightly softer than pure black.
+- **Ink Muted 48** (`{colors.ink-muted-48}` — #7a7a7a): Disabled button text and legal fine-print.
+
+### Hairlines & Borders
+- **Divider Soft** (`{colors.divider-soft}` — #f0f0f0): The "border" tone on secondary buttons — functions as a ring shadow rather than a hard line. In production, often applied as `rgba(0, 0, 0, 0.04)`.
+- **Hairline** (`{colors.hairline}` — #e0e0e0): The 1px hairline border on store utility cards and configurator chips.
+
+### Brand Gradient
+**No decorative gradients.** Atmospheric depth on product photography (the iPhone 17 Pro camera plate, the Apple Watch bands, AirPods reflections) is inherent to the imagery, not a CSS gradient overlay. The environment page's hero uses photographic atmosphere (mountain vista at dawn) but no gradient tokens are defined. Apple is the rare luxury-brand site with zero gradient-based design tokens.
+
+## Typography
+
+### Font Family
+- **Display**: `SF Pro Display, system-ui, -apple-system, sans-serif` — Apple's proprietary display face, optimized for sizes ≥ 19px. Defines the voice of every headline.
+- **Body / UI**: `SF Pro Text, system-ui, -apple-system, sans-serif` — the text-optimized variant used for body copy, captions, buttons, and links below 20px.
+- **OpenType features**: `font-variant-numeric: numerator` is enabled on numeric links (pricing tables, spec sheets). Display sizes rely on tight tracking rather than contextual ligatures.

+| `{typography.button-large}` | 18px | 300 | 1.0 | 0 | Store hero CTAs (the rare weight 300) |
+| `{typography.button-utility}` | 14px | 400 | 1.29 | -0.224px | Utility/nav button labels |
+| `{typography.fine-print}` | 12px | 400 | 1.0 | -0.12px | Fine-print, footer body |

+| `{typography.nav-link}` | 12px | 400 | 1.0 | -0.12px | Global nav menu items |
+
+### Principles
+
+- **Negative letter-spacing at display sizes.** Every headline at 17px and up carries a slight tracking tighten (`-0.12 → -0.374px`). This produces the iconic "Apple tight" headline cadence. Never used at 12px or below.
+- **Body copy at 17px, not 16px.** Apple breaks the SaaS convention and runs paragraph text at 17px. The extra pixel gives the page an unmistakable "reading, not scanning" pace.
+- **Weight 300 is real and rare.** Used deliberately on a handful of large-size reads (`{typography.button-large}` at 18px/300 and `{typography.lead-airy}` at 24px/300). It's not an accident — it's a light-atmosphere cue reserved for moments where the content should feel airy.
+- **Weight 600, not 700, for headlines.** Apple's headlines sit at weight 600. Weight 700 is used sparingly for `{typography.tagline}` (21px) when a touch more assertion is needed.
+- **Line-height is context-specific.** Display sizes use 1.07–1.19 (tight). Body uses 1.47. Utility link stacks in the footer/store use an unusually relaxed 2.41 (`{typography.dense-link}`). The 2.41 is not a bug — it's how the footer's dense link columns breathe.
+- **Weight 500 is deliberately absent.** The ladder is 300 / 400 / 600 / 700. Mid-weight readings always use 600.
+
+### Note on Font Substitutes
+SF Pro is Apple's proprietary system font. When building off-system:
+
+- Use `system-ui, -apple-system, BlinkMacSystemFont` as the first stack entry — on macOS/iOS/Safari this resolves to the real SF Pro.
+- For non-Apple platforms, **Inter** (Google Fonts, variable) is the closest open-source equivalent. Inter at weight 600 with `font-feature-settings: "ss03"` approximates SF Pro's rounded "a" character.
+- Nudge `letter-spacing` down by `-0.01em` on display sizes to re-create the Apple tight feel; Inter's default tracking runs slightly wider than SF Pro.
+- For body text, tighten line-height by `0.03` (from 1.47 → 1.44) when substituting Inter — Inter's taller x-height needs less leading.
+
+## Layout
+
+### Spacing System
+- **Base unit:** 8px. Sub-base values (2, 4, 5, 6, 7) are used for tight typographic adjustments; structural layout snaps to 8/12/16/20/24.
+- **Tokens:** `{spacing.xxs}` 4px · `{spacing.xs}` 8px · `{spacing.sm}` 12px · `{spacing.md}` 17px · `{spacing.lg}` 24px · `{spacing.xl}` 32px · `{spacing.xxl}` 48px · `{spacing.section}` 80px.
+- **Section vertical padding:** `{spacing.section}` (80px) inside a product tile; tiles stack edge-to-edge with 0 gap (the color change provides the break).
+- **Card padding:** `{spacing.lg}` (24px) inside utility grid cards.
+- **Button padding:** 8–11px vertical, 15–22px horizontal.
+- **Universal rhythm constants:** the 17px body line-height multiplier (~25px line) and 21px tagline size show up on every analyzed page.
+
+### Grid & Container
+- **Max content width:** ~980px on text-heavy sections (environment), ~1440px on product grids (store, accessories), full-bleed for product tiles (homepage).
+- **Column patterns:** 3 to 5 column utility card grid on store/accessories; 2-column side-by-side tiles on homepage occasional sections; single-column centered stack on product tile heroes.
+- **Gutters:** 20–24px between cards in a utility grid.
+
+### Whitespace Philosophy
+Apple's whitespace is the product's pedestal. Every tile begins with at least 64px of air above its headline and 48–64px below. Product renders are never crowded; the nearest content to a product image is at least 40px away. The footer is the only area that breaks this — there, Apple goes deliberately dense to make the full information architecture visible at a glance.
+
+## Elevation & Depth
+
+| Level | Treatment | Use |
+|---|---|---|
+| Flat | No shadow, no border | Full-bleed tiles, global nav, footer, body sections |
+| Soft hairline | 1px `rgba(0, 0, 0, 0.08)` border | Utility cards, sub-nav frosted-glass separator |
+| Backdrop blur | `backdrop-filter: blur(N)` on Parchment 80% | Sub-nav and the iPhone buy floating sticky bar |
+| Product shadow | `rgba(0, 0, 0, 0.22) 3px 5px 30px 0` | Product renders resting on a surface (the only true "shadow" in the system) |
+
+**Shadow philosophy.** Apple uses **exactly one** drop-shadow, and it is applied to photographic product imagery — never to cards, never to buttons, never to text. Elevation in the UI comes from (a) surface-color change (light tile ↔ dark tile) and (b) backdrop-blur on sticky bars. The single shadow is about giving the product weight, not about UI hierarchy.
+
+### Decorative Depth
+- **Atmospheric imagery** on the environment page (photographic vista) supplies mood; no CSS gradient involved.
+- **Edge-to-edge tile alternation** creates rhythm without borders or shadows — the color change itself is the divider.
+- **Backdrop-filter blur** on `{component.sub-nav-frosted}` and `{component.floating-sticky-bar}` creates a "floating over content" effect that's functional, not decorative.
+
+## Shapes
+
+### Border Radius Scale
+
+| Token | Value | Use |
+|---|---|---|
+| `{rounded.none}` | 0px | Full-bleed product tiles (no corner rounding) |
+| `{rounded.xs}` | 5px | Inline links when styled as subtle chips (rare) |
+| `{rounded.sm}` | 8px | Dark utility buttons (Sign In, Bag), inline card imagery |
+| `{rounded.md}` | 11px | White Pearl Button capsules |
+| `{rounded.lg}` | 18px | Store utility cards, accessories grid cards |
+| `{rounded.pill}` | 9999px | Primary blue pill CTAs, sub-nav buy button, configurator option chips, search input — the signature Apple pill |
+| `{rounded.full}` | 9999px / 50% | Circular control chips floating over photography |
+
+### Photography Geometry
+- **Hero imagery**: full-bleed, 21:9 or taller on the homepage; 16:9 on environment and shop pages. Product renders are photographic-realistic, often shot on a tinted surface that becomes the tile background.
+- **Product renders**: PNG/WebP with transparency; rest on a surface tile and pick up the system shadow.
+- **Accessory grid**: square 1:1 crops at `{rounded.lg}` (18px) radius, light neutral backgrounds, product centered with 20–40px internal padding.
+- **No rounded imagery in hero tiles** — images are full-bleed rectangular. Rounding (`{rounded.sm}`, `{rounded.lg}`) appears only on inline card imagery.
+- Lazy-loading via responsive `srcset` and `sizes` across all breakpoints; CDN-optimized WebP.
+
+## Components
+
+### Top Navigation
+
+**`global-nav`** — Persistent, ultra-thin black nav bar pinned to the top of every page. Background `{colors.surface-black}`, height 44px, text `{colors.on-dark}` in `{typography.nav-link}` (12px / 400 / -0.12px tracking). Links are quiet, spaced ~20px apart, running edge-to-edge across the top. Right-aligned cluster: Search, Bag icons — always visible. On mobile, collapses to hamburger at ~834px and the Apple logo centers.
+
+**`sub-nav-frosted`** — Surface-specific nav that sticks below the global nav. Background `{colors.canvas-parchment}` at 80% opacity with backdrop-filter blur, creating a frosted-glass effect. Height 52px. Content on left: product category name ("iPhone", "Store", "Accessories") in `{typography.tagline}` (21px / 600). Content right: inline nav links in `{typography.button-utility}` (14px), ending in a persistent `{component.button-primary}` ("Buy") or a utility link.
+
+### Buttons
+
+**`button-primary`** — The signature Apple action. Background `{colors.primary}` (Action Blue #0066cc), text `{colors.on-primary}` in `{typography.body}` (SF Pro Text 17px / 400), rounded `{rounded.pill}` (full pill — capsule-shaped), padding 11px × 22px. The full-pill radius IS the brand action signal.
+- Active state: `{component.button-primary-active}` — `transform: scale(0.95)` (the system-wide micro-interaction).
+- Focus state: `{component.button-primary-focus}` — 2px solid `{colors.primary-focus}` outline.
+
+**`button-secondary-pill`** — Used as the second CTA when two blue pills appear together ("Learn more" / "Buy"). Background transparent, text `{colors.primary}`, 1px solid `{colors.primary}` border, rounded `{rounded.pill}`, padding 11px × 22px. Reads as a "ghost pill."
+
+**`button-dark-utility`** — Global nav actions (Sign In, Bag, language selector). Background `{colors.ink}` (#1d1d1f), text `{colors.on-dark}` in `{typography.button-utility}` (14px / 400 / -0.224px tracking), rounded `{rounded.sm}` (8px), padding 8px × 15px. Active state shrinks via `transform: scale(0.95)`.
+
+**`button-pearl-capsule`** — Product-card secondary button. Background `{colors.surface-pearl}` (#fafafc), text `{colors.ink-muted-80}` in `{typography.caption}` (14px), 3px solid `{colors.divider-soft}` border (functions as a soft ring rather than a visible line), rounded `{rounded.md}` (11px), padding 8px × 14px.
+
+**`button-store-hero`** — A larger primary CTA used on store hero surfaces. Same Action Blue + Paper White as `{component.button-primary}`, but with `{typography.button-large}` (18px / 300 — note the rare weight 300) and slightly more padding (14px × 28px). Used sparingly on the store landing.
+
+**`button-icon-circular`** — Floats over photography. 44 × 44px, background `{colors.surface-chip-translucent}` at ~64% alpha, icon in `{colors.ink}`, rounded `{rounded.full}`. Used for carousel controls, close buttons, and in-image controls (product image thumbnails on the iPhone buy page).
+
+**`text-link`** — Inline body links in `{colors.primary}` (Action Blue). Underlined or non-underlined per context.
+
+**`text-link-on-dark`** — Inline body links on dark tiles in `{colors.primary-on-dark}` (Sky Link Blue #2997ff) — Action Blue would disappear against `{colors.surface-tile-1}`.
+
+### Cards & Containers
+
+**`product-tile-light`** — Full-bleed light tile. Background `{colors.canvas}` (white), text `{colors.ink}`, rounded `{rounded.none}` (0 — tiles touch edges), vertical padding `{spacing.section}` (80px). Centered stack: product name in `{typography.display-lg}` (40px / 600) → one-line tagline in `{typography.lead}` (28px / 400) → two `{component.button-primary}` CTAs ("Learn more" / "Buy") → product render resting on the surface with the system shadow.
+
+**`product-tile-parchment`** — Same as `{component.product-tile-light}` but on `{colors.canvas-parchment}` (#f5f5f7). Used to break two consecutive white tiles.
+
+**`product-tile-dark`** — Full-bleed dark tile. Background `{colors.surface-tile-1}` (#272729), text `{colors.on-dark}`, rounded `{rounded.none}`, vertical padding `{spacing.section}` (80px). Same content stack as the light tile but with `{component.text-link-on-dark}` for inline copy and `{component.button-primary}` (Action Blue still works on the dark surface). Used on the homepage product grid as the alternating dark band.
+
+**`product-tile-dark-2`** — Variant on `{colors.surface-tile-2}` (#2a2a2c). Used where a dark tile sits directly above or below `{component.product-tile-dark}` to create the faintest separation through micro-step lightness change.
+
+**`product-tile-dark-3`** — Variant on `{colors.surface-tile-3}` (#252527). Used at the bottom of the stack and in embedded video/player frames.
+
+**`store-utility-card`** — Used in store grid and accessories grid. Background `{colors.canvas}` (white), 1px solid `{colors.hairline}` border, rounded `{rounded.lg}` (18px), padding `{spacing.lg}` (24px). Top: product image (1:1 crop with `{rounded.sm}` (8px) inner image radius). Below: product name in `{typography.body-strong}` (17px / 600), price in `{typography.body}` (17px / 400), and a `{component.text-link}` ("Buy" or "Learn more"). No shadow by default; product render itself carries the system product-shadow.
+
+**`configurator-option-chip`** — Pill-shaped tappable cell used in the iPhone 17 Pro buy page. Background `{colors.canvas}`, text `{colors.ink}` in `{typography.caption}`, rounded `{rounded.pill}`, padding 12px × 16px. Contains a small product thumbnail + label + price delta. Arranged in a grid of 4–5 options per row.
+
+**`configurator-option-chip-selected`** — Selected state. Border upgrades to 2px solid `{colors.primary-focus}`. Same shape, same content.
+
+**`environment-quote-card`** — A photographic-canvas hero specific to the environment page. Dark photographic backdrop (mountain vista at dawn) with `{colors.surface-tile-1}` as the fallback color, centered white-text headline in `{typography.display-lg}` (40px), small green "Apple 2030" pictographic logo above the headline, single `{component.button-primary}` below. Padding `{spacing.section}` (80px).
+
+**`floating-sticky-bar`** — Floats at the bottom of the viewport on the iPhone 17 Pro buy page during scroll. Background `{colors.canvas-parchment}` at 80% opacity with `backdrop-filter: blur(N)`, height 64px, padding 12px × 32px. Left: running price total in `{typography.body}`. Right: `{component.button-primary}` ("Add to Bag").
+
+### Inputs & Forms
+
+**`search-input`** — The accessories search input. Background `{colors.canvas}`, text `{colors.ink}` in `{typography.body}` (17px), 1px solid `rgba(0, 0, 0, 0.08)` border, rounded `{rounded.pill}` (full pill — search is also pill-shaped, matching the CTA grammar), padding 12px × 20px, height 44px. Leading icon: search glyph at 14px, muted tint.
+
+Error and validation states were not surfaced in the analyzed pages.
+
+### Footer
+
+**`footer`** — Background `{colors.canvas-parchment}` (#f5f5f7), text `{colors.ink-muted-80}`. Link columns in `{typography.dense-link}` (17px / 400 / 2.41 line-height — the relaxed leading is what makes the dense columns scannable). Column headings in `{typography.caption-strong}` (14px / 600). Legal row at the very bottom in `{typography.fine-print}` (12px / 400) with `{colors.ink-muted-48}` text. Vertical padding 64px.
+
+## Do's and Don'ts
+
+### Do
+- Use `{colors.primary}` (Action Blue #0066cc) for every interactive element — links, pill CTAs, focus signals — and nothing else. The single accent is non-negotiable.
+- Set headlines in `{typography.hero-display}` or `{typography.display-lg}` with negative letter-spacing (`-0.28 → -0.374px`) to get the signature "Apple tight" cadence.
+- Run body copy at `{typography.body}` (17px / 400 / 1.47 / -0.374px) — not 16px. The extra pixel defines the brand's reading pace.
+- Alternate `{component.product-tile-light}` (or parchment) and `{component.product-tile-dark}` for full-bleed section rhythm. The color change IS the divider.
+- Reserve `{rounded.pill}` for the primary blue CTA and any other element that should read as an "action" (configurator chips, search input, sticky bar CTA).
+- Apply the single product-shadow (`rgba(0, 0, 0, 0.22) 3px 5px 30px`) only to product renders resting on a surface — never on cards, buttons, or text.
+- Use `transform: scale(0.95)` as the active/press state on every button — it's the system-wide micro-interaction.
+- Keep the global nav `{colors.surface-black}` (true black) — it's the only place pure black appears on most pages.
+
+### Don't
+- Don't introduce a second accent color; every "click me" signal is `{colors.primary}` (Action Blue).
+- Don't add shadows to cards, buttons, or text — shadow is reserved for product imagery.
+- Don't use gradients as decorative backgrounds; atmosphere comes from photography.
+- Don't set body copy at weight 500 — Apple's ladder is 300 / 400 / 600 / 700, with 500 deliberately absent. Body is always 400; strong inline is 600; display is 600.
+- Don't round full-bleed tiles — tiles are rectangular and edge-to-edge; the color change is the divider.
+- Don't tighten line-height below 1.47 for body copy — the editorial leading is part of the brand.
+- Don't mix radii grammars — use `{rounded.sm}` for compact utility, `{rounded.lg}` for utility cards, `{rounded.pill}` for pills, and nothing in between (except the rare `{rounded.md}` Pearl Button).
+- Don't use `{colors.primary-on-dark}` (Sky Link Blue) on light surfaces — it's the dark-tile-only variant. Action Blue is for light surfaces.
+
+## Responsive Behavior
+
+### Breakpoints
+
+| Name | Width | Key Changes |
+|---|---|---|
+| Small phone | ≤ 419px | Single-column tiles; sub-nav collapses to category name + primary CTA only; hero typography drops to 28px |
+| Phone | 420–640px | Single-column stack; product renders scale to 80% of tile width; hero h1 drops to 34px |
+| Large phone | 641–735px | Tiles transition to tighter padding (48px vertical vs 80px); fine-print wraps |
+| Tablet portrait | 736–833px | Global nav collapses to hamburger; sub-nav hides category chips, keeps primary CTA |
+| Tablet landscape | 834–1023px | Global nav returns fully expanded; 3-column utility grids become 2-column |
+| Small desktop | 1024–1068px | Product tiles use 2/3 width with margin gutters; hero h1 stays at 40px |
+| Desktop | 1069–1440px | Full layout; 4–5 column store grids; 1440px content max |
+| Wide desktop | ≥ 1441px | Content locks at 1440px, margins absorb extra width |
+
+The structural breakpoints that matter for agents: 1440px (content lock), 1068px (small-desktop), 833px (tablet landscape switch), 734px (tablet portrait), 640px (phone), 480px (small phone).
+
+### Touch Targets
+- Minimum 44 × 44px. `{component.button-primary}` lands at ~44 × 100px (with the full-pill radius making the visible hit area more generous than the label suggests).
+- `{component.button-icon-circular}` is exactly 44 × 44px.
+- Global nav utility links are smaller (~32 × 80px) — they deliberately sit at a tighter target because they're precision desktop actions, and the mobile hamburger replaces them at ≤ 833px.
+
+### Collapsing Strategy
+- **Global nav**: full horizontal link row on desktop → collapses to Apple logo + hamburger + bag icon at 834px and below.
+- **Sub-nav**: category name + inline links + primary CTA → category name + primary CTA only at mobile; inline links move into a hamburger tray.
+- **Product tiles**: stack from 2-column to 1-column at 834px; vertical padding tightens from 80px → 48px at small-phone.
+- **Utility grids** (store, accessories): 5-col → 4-col (1440px) → 3-col (1068px) → 2-col (834px) → 1-col (640px).
+- **Hero typography**: `{typography.hero-display}` (56px) → `{typography.display-lg}` (40px) at 1068px → 34px at 640px → 28px at 419px.
+
+### Image Behavior
+- All product imagery uses responsive `srcset` with breakpoint-matched crops.
+- Hero photography may switch art direction at mobile (e.g., the environment page's vista crops to a taller aspect ratio on mobile, framing the subject differently).
+- Product renders maintain their 1:1 or 4:3 aspect ratios across breakpoints; only scale changes.
+- Lazy-loading is default; the above-fold hero loads eagerly.
+
+## Iteration Guide
+
+1. Focus on ONE component at a time. Reference its YAML key directly (`{component.product-tile-dark}`, `{component.search-input}`).
+2. Variants of an existing component (`-active`, `-focus`, `-2`, `-3`) live as separate entries in `components:`.
+3. Use `{token.refs}` everywhere — never inline hex.
+4. Never document hover. Default and Active/Pressed states only.
+5. Display headlines stay SF Pro Display 600 with negative letter-spacing. Body stays SF Pro Text 400 at 17px. The boundary is unbreakable.
+6. The single drop-shadow (`rgba(0, 0, 0, 0.22) 3px 5px 30px`) is reserved for product photography only.
+7. When in doubt about emphasis: alternate surface (light → dark tile) before adding chrome.
+
+## Known Gaps
+
+- Form validation and error states were not surfaced on the analyzed pages; only the neutral search input is documented.
+- The homepage's embedded video/player frame uses `{colors.surface-black}`; interior player controls are not documented (they're a platform widget, not a web-design token).
+- Some component imagery is dynamic (rotating product hero) and its specific copy varies per surface — component specs name the structure, not the rotating content.
+- Dark-mode counterparts for store and accessories utility cards were not surfaced on the analyzed pages; the system documented is the daytime/light-dominant variant Apple ships by default.
+- Atmospheric photography (environment page mountain vista) is a content asset, not a design token; the documented `{component.environment-quote-card}` describes the structural surface only.
+- The exact backdrop-filter blur radius on `{component.sub-nav-frosted}` and `{component.floating-sticky-bar}` is platform-dependent; production CSS uses `saturate(180%) blur(20px)` as a typical baseline but the value isn't formalized as a token.

+## 2026-06-06
+
+- Fixed the desktop Dock so route changes from Dock menu links no longer leave focus-held open state behind when the Dock is not pinned.
+- Kept the saved `dock-pinned-v2` preference unchanged during navigation and only released transient Dock focus/hover state after menu clicks and pathname changes.
+- Validation: `npm run lint` passed and `npm run build` passed. In-app browser verification on `http://localhost:3111/` confirmed that after unpinning the Dock, clicking the Dock archive menu navigates to `/archive`, the pin button remains `aria-pressed=false`, and the Dock collapses after the pointer leaves.
+- Recommended next task: do one visual pass on the Dock at narrow desktop widths to confirm the collapse animation still feels smooth around the sidebar offset.
+
+## 2026-06-02
+
+- Refined the public layout after desktop/mobile review: the shell now guards horizontal overflow, uses route-aware bottom padding, hides the top menubar on mobile, and opens the mobile sidebar/search panel from the Dock.
+- Reworked the Dock so mobile uses it as the primary navigation hub, while desktop keeps a folded Dock that expands on hover/focus and includes a pin toggle.
+- Smoothed the desktop Dock hide/show interaction by separating hover-open, closing, and fully-collapsed states; the Dock now keeps the expanded hit area during the closing animation so re-entering mid-collapse reverses smoothly.
+- Changed the desktop Dock's default state to pinned/open and added distinct soft pastel tones to Dock buttons, including stronger visual treatment for pin/unpin and auth actions.
+- Softened the Dock button palette to quieter pastel tones and made the light-mode Dock bar read as a cleaner white glass surface.
+- Fixed the Dock pin toggle so mouse-based unpinning no longer leaves button focus holding the Dock open, and changed the Dock Home button to a white neutral tone.
+- Reworked the Dock material away from cute pastel tiles into a more macOS-like neutral frosted glass texture with translucent white glass buttons.
+- Corrected the Dock button direction so only Home stays white, while the other actions keep subtle pastel tints with a translucent macOS-style glass material.
+- Increased Dock button translucency contrast so the buttons remain glassy while sitting slightly more opaque than the Dock background.
+- Rebalanced the home page around latest posts with popular posts as a supporting panel, converted the post detail page into a quieter reader surface, and hardened Markdown/code/table wrapping against mobile overflow.
+- Added a client-side archive explorer with year, month, category, and compact/comfort density controls over the existing server-fetched post list.
+- Rebuilt the chess page with safer viewport-aware board sizing, quieter puzzle panels, and enough layout clearance for the Dock.
+- Validation: `npm run lint` passed and `npm run build` passed. In-app browser verification on a local `next start` server confirmed no horizontal overflow on `/`, `/archive`, and `/play/chess` at mobile width, mobile Dock-centered navigation opens the sidebar panel without overflow, desktop CSS loads, the mobile Dock is hidden on desktop, and the desktop Dock starts folded with a pin control. The live chess board itself could not be verified because the local backend chess API was unavailable, so `/play/chess` rendered the error state.
+- Validation: `npm run lint` passed and `npm run build` passed. In-app browser verification on a local `next start` server confirmed the desktop Dock starts as a small bottom tab, uses 560ms transitions for tab/panel geometry, and expands into the larger Dock hit area when opened.
+- Validation: `npm run lint` passed and `npm run build` passed. In-app browser verification on a local `next start` server confirmed the Dock opens by default and Home/Archive/Chess/Login/Signup/Pin buttons render distinct pastel colors.
+- Validation: `npm run lint` passed and `npm run build` passed. In-app browser verification on `http://localhost:3106/` confirmed the light-mode Dock bar renders as a cleaner white glass surface and the Dock button colors use quieter pastel tones.
+- Validation: `npm run lint` passed and `npm run build` passed. In-app browser verification on `http://localhost:3107/` confirmed the Dock Home button renders white and mouse-based unpinning collapses the Dock after the pointer leaves.
+- Validation: `npm run lint` passed and `npm run build` passed. In-app browser verification on `http://localhost:3108/` confirmed the Dock uses neutral translucent glass material, with non-home buttons rendering as subtle white glass rather than pastel color tiles.
+- Validation: `npm run lint` passed and `npm run build` passed. In-app browser verification on `http://localhost:3109/` confirmed Home stays white while the other Dock buttons keep pastel-tinted translucent glass backgrounds with button-level blur.
+- Validation: `npm run lint` passed and `npm run build` passed. In-app browser verification on `http://localhost:3110/` confirmed Dock buttons remain translucent but render slightly more opaque than the Dock background for clearer contrast.
+- Recommended next task: run a browser pass against a reachable backend API, especially one real post detail route and the populated chess puzzle board, then tune any remaining content-specific long-title or board-height edge cases.
+
+## 2026-05-29
+
+- Fixed post detail 404s caused by double-encoding dynamic route slugs that already arrive percent-encoded from URLs such as `/posts/soft-delete%2C-hard-delete`.
+- Updated the public post fetch helper to decode a route slug once before encoding it for the backend API path, preserving normal Korean/special-character slug requests while avoiding `%252C`-style API lookups.
+- Validation: `npm run lint` passed and `npm run build` passed. A local production server with `NEXT_PUBLIC_API_URL=https://blogserver.wypark.me` returned real post titles for `/posts/soft-delete%2C-hard-delete`, `/posts/destructuring-%26-component%ED%95%A8%EC%88%98`, and `/posts/rtr-(refresh-token-rotation)`.
+- Recommended next task: deploy the slug normalization fix before re-checking affected live post URLs in Search Console or the browser.
+- Added a category post-list page size control with 9/18/27 options, defaulting to 9 and persisting the user's choice in `localStorage` under `categoryPageSize`.
+- Wired the selected category page size into the React Query key and `getPostsByCategory` request size, resetting to page 1 when the size changes while preserving search behavior.
+- Adjusted the category page toolbar so search, page-size controls, and grid/list controls stack cleanly on narrow screens and align in one row on desktop.
+- Validation: `npm run lint` passed and `npm run build` passed. Static verification confirms the category query uses `pageSize` and the page-size selector persists to `localStorage`; interactive browser verification was skipped because no local browser/Playwright automation runtime is available in this environment.
+- Recommended next task: verify the category toolbar in a real browser after deploy, especially mobile widths and the 18/27 page-size transitions.
+- Investigated Google Search Console crawlability concerns for the live site.
+- Checked live `robots.txt`, `sitemap.xml`, homepage, sample post pages, and backend post API with a Googlebot user agent; public post URLs in the sitemap returned 200 with no `X-Robots-Tag` or meta robots block.
+- Confirmed the non-www production host `blog.wypark.me` is the relevant host; its home/archive initial HTML currently contains no `/posts/` links because public lists are client-side rendered.
+- Identified crawlability risk areas: home/archive rely on client-side post-list fetching, local builds generate a static-only sitemap when the backend API is unreachable, sitemap `lastmod` values can be timezone-skewed when backend timestamps omit an offset, and canonical URLs are not currently emitted.
+- Validation: `npm run build` passed. As expected without a local backend, build-time sitemap generation logged `fetch failed` and produced only static sitemap entries in the local `.next` output.
+- Converted home and archive pages to server-rendered public post lists through a dedicated `src/api/publicPosts.ts` fetch helper so first HTML now includes discoverable `/posts/` links.
+- Added centralized site metadata utilities, canonical metadata for public pages/posts, dynamic sitemap generation, KST-aware API date parsing for `lastmod`, and robots/site URL reuse.
+- Validation: `npm run lint` passed and `npm run build` passed. A local production server with `NEXT_PUBLIC_API_URL=https://blogserver.wypark.me` returned 22 `/posts/` links on `/`, 204 on `/archive`, canonical URLs for both pages, and sitemap output with 104 URLs including 102 post URLs.
+- Recommended next task: deploy the SEO crawlability fix, then resubmit `https://blog.wypark.me/sitemap.xml` and a representative post URL in Google Search Console URL Inspection.
+- Redesigned the app shell into a macOS-inspired blog OS with pastel desktop background tokens, translucent menu bar, quick-launch Dock, and reusable window surfaces.
+- Applied the window treatment to the home dashboard, post reader, archive, category view, auth screens, chess puzzle view, and admin management shells.
+- Restored the missing local `chess.js` install in `node_modules` so build verification could run; no dependency version changes were intended.
+- Refined the desktop layout after review: the sidebar can now collapse on PC, the main window width is more consistent across dashboard/list/reader/chess/admin views, the sidebar archive shortcut was removed, and the top menu now uses WYPark branding with GitHub/email links plus theme switching only.
+- Moved auth/admin/write/logout actions into the Dock and changed category windows/menu labels to show the actual category name instead of Finder/posts copy.
+- Tuned the follow-up layout: main content now centers inside the area remaining after the desktop sidebar, sidebar GitHub/email shortcuts were removed, top-bar GitHub/email links now sit as plain left-side menu items, and the home labels were simplified to 홈/WYPark.
+- Softened the home dashboard inner popular/latest sections so they no longer render as nested macOS windows with traffic-light controls; they now read as embedded dashboard panels inside the WYPark window.
+- Rebuilt the admin post writing screen as a glassy Markdown Studio with a larger writing area, publish controls, category/tag/image/draft panels, and fixed MDEditor foreground colors so typed text remains readable in both light and dark themes.
+- Hardened the Markdown editor text visibility fix by binding the editor color mode to the app's resolved theme and forcing the real textarea layer to use `--color-text` while hiding the syntax overlay text layer that could inherit the wrong contrast.
+- Validation: `npm run lint` passed, `npm run build` passed. The build logged a sitemap fetch warning because the backend API at the local default was not reachable, but the command completed successfully.
+- Browser verification: previously started this app on `http://localhost:3100` because ports 3000 and 3001 were already occupied; confirmed desktop background gradients, menu bar, Dock, and window surfaces on `/`, `/archive`, and `/login`. For this follow-up, the dev/standalone server started successfully in foreground but exited when launched as a background non-interactive process, so browser verification was skipped after lint/build passed.
+- Recommended next task: review the remaining older Korean strings in admin/editor flows and normalize any mojibake that predates this redesign.
+- Unified the macOS-inspired layer system by splitting window, card, control, sidebar, menu bar, and Dock border/shadow/blur tokens, with stronger dark-mode card separation.
+- Applied the layer tokens across shared surfaces, the menu bar, Dock, sidebar controls, search/toggles, home dashboard panels, reader navigation cards, and admin dashboard/editor panels.
+- Validation: `npm run lint` passed, `npm run build` passed, and in-app browser verification on `http://localhost:3100/` confirmed distinct light/dark computed border, shadow, and backdrop blur values for the menu bar, main window, internal cards, and Dock.
+- Recommended next task: do a visual pass on lower-traffic admin list/modal screens and convert any remaining ad hoc hover fills to the shared card/control tokens.
