/* ════════════════════════════════════════════════════════════════
   Teacher LMS dashboard — screen structure & visual design only.
   Fixed 1920×1080 canvas (scaled by #game-root --game-scale, same
   convention as other stages). Only the main content scrolls.
   All selectors are prefixed with `teacher-lms-` to avoid leaking
   into other scenes. Legacy body-level rule stays in
   teacher-dashboard.css.
