/* InventorySystem's copy of Gradebook's design system: same tokens (colors, radii,
   shadows, type), same top-nav-bar/card/button/table/pill/modal shapes, same
   data-theme light/dark switch. Trimmed to the generic, reusable core -- Gradebook's
   own theme.css also has ~1800 lines of domain-specific rules (timecards, student
   dashboards, notification push, account-avatar cropping) that don't apply here.
   Targets MudBlazor's own class names directly so existing MudCard/MudButton/MudTable/
   MudDialog components pick up the look without being rewritten as raw HTML. */
