   RotaFlux UI — hand-written design system layer.

   Loaded after tailwind.min.css. Owns the shared visual language (tokens,
   cards, buttons, badges, banners, tables, form controls, page scaffolding)
   so templates stop carrying one-off inline styles. Plain CSS on purpose:
   no build step required, works even when the Tailwind bundle is stale.
