 - 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.
