/* ══════════════════════════════════════════════════════════════════════════
   Corebalt Back Office — shared design system (docs/platform/ui-style.md).
   Soft neutral canvas, white panels, fine borders, high-contrast text; brand blue only for the primary
   action and meaningful states; navy rail. Every colour is a token below, so the light and dark themes
   are one set of rules. Every page styles itself through these shared classes (.card, table, button,
   input, .pill, .toolbar, .row ...): restyling here restyles the whole back office.
   Theme: follows the system; <html data-theme="light|dark"> (the top bar's switch) overrides it.
