+- Reworked the macOS-inspired shell into a fuller desktop illusion: full-width system menu bar, floating Finder-style sidebar window, viewport-centered Dock, desktop wallpaper layers, and desktop shortcut icons for major destinations.
+- Rebuilt the public home screen as a Finder window with a locations sidebar, disk/status strip, file-like post rows, Spotlight-style search results, and stronger shared window glass treatment.
+- Extended the OS treatment across archive, category, reader, login/signup, admin shell, post cards, and list rows, including file icons, Reader window framing, and cleanup of a stale mojibake notice-category check.
+- Validation: `npm run lint` passed and `npm run build` passed. In-app browser verification on `http://localhost:3112/`, `/archive`, and `/login` confirmed no horizontal overflow, desktop/mobile menu and Dock visibility rules, shared window surfaces, and no browser console warnings/errors. The default local API data rendered empty post states during the browser pass.
+- Recommended next task: run a visual pass against `NEXT_PUBLIC_API_URL=https://blogserver.wypark.me` so populated post lists and one real reader page can be tuned with long Korean titles and real content.
+
 - 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.
