/* Instructor review workspace (/instructor/*) — InstructorLayout, WritingReviewQueuePage and
   WritingReviewScorePage.
   Added: 2026-10-22 by Niloy (in admin-panel.css). Moved here on 2026-10-22 so instructor-only
   styles no longer live in the shared admin shell file.

   Load order matters: App.razor links this AFTER admin-panel.css, because the instructor pages sit
   inside the same .ap-admin-* shell and a few rules here deliberately refine shell rules
   (.ap-instructor-actions over .ap-admin-actions, the two-column topbar over .ap-admin-topbar).
   Every selector is .ap-instructor-* / .instructor-* prefixed, so the file has no effect on other pages. */

/* ── Layout chrome ─────────────────────────────────────────────────────────── */

/* The admin topbar is a 3-column grid (title | centred tabs | actions). The instructor area has no
   top tabs, so it uses two columns rather than an empty placeholder <div> in the middle slot. The
   ≤900px rule in admin-panel.css (.ap-admin-topbar → one column) is matched by the media block at
   the bottom of this file, since this file loads later and would otherwise win at that width. */
