/* LTDC LMS design system.
   Layout follows the school's current LMS (white top bar with the seal and term, icon sidebar,
   breadcrumbs, class header card, tabbed class page, dark mode) with one brand colour throughout.
   --brand and --accent come from Settings → Branding (set on :root by js/shell.js);
   every shade is mixed from them, so any school colour works. */
