/* RCCG GTP Learning Portal - shared design system (tokens, Bootstrap overrides, components).
   Brand: navy #000080 for structure, orange #FFA500 as the one accent (filled, with navy text: orange text on white
   is too faint to read). Type: Bricolage Grotesque for headings, Atkinson Hyperlegible Next for reading, its Mono for
   code. Radius follows hierarchy (panels 20, cards 14, controls 10); borders separate things, shadows only lift what
   floats (menus, dialogs, toasts). Mobile-first; every component works from 320px up.
   The --g-* names are historical (the first theme was green); they now hold the navy scale. */
