+- Fixed admin pages being pushed outside the visible content area by removing viewport-based `md:w-[80vw]` widths from the admin route shell and Markdown editor container.
+- Changed admin containers to use the remaining shell content width (`w-full` with `max-w-[1400px]`) so the sidebar margin no longer combines with an extra viewport-width layout.
+- Validation: `npm run lint` passed and `npm run build` passed. Authenticated browser verification was not possible in the current session because `/admin` redirects to login without an admin token.
+- Recommended next task: verify `/admin` and `/admin/posts/new` in an authenticated browser session at desktop widths around 1280px and 1440px.

 - Fixed the admin dashboard traffic chart visibility by giving bar columns a real height context, so percentage-based bar heights render instead of collapsing.
 - Added fallback traffic points from recent/popular post data when the dashboard API or `traffic` array is empty, keeping the graph visible while the backend traffic aggregation is unavailable.
 - Validation: `npm run lint` passed and `npm run build` passed. Browser navigation to `/admin` was attempted on `http://localhost:3112/`, but the current browser session was unauthenticated and rendered the login screen, so the admin chart itself was validated by code path and build checks rather than a live authenticated screenshot.
