   Loaded on EVERY page. It holds only what genuinely belongs to
   every screen: theme tokens, the app shell, topbar/sidebar,
   shared components (cards, tables, forms, buttons, badges) and
   the motion vocabulary.

   Anything that exists on ONE screen lives in its own file under
   css/pages/<Controller>.css and is auto-included by _Layout —
   see "Per-page stylesheets" in CLAUDE.md. Reusable component
   bundles that only some pages need (css/charts.css) are pulled
   in by those pages through @section Styles.

   Do not park page-specific rules here. That is what turned this
   file into 1,300 lines nobody could safely edit.
