   xrprints UI kit (shadcn/ui-inspired). Loaded after styles.css/tools.css.

   1. Tokens (--ui-*): neutral zinc palette, hairline borders, 8px radius,
      soft layered shadows. The indigo brand colour stays as an accent.
   2. Components (.ui-*): buttons, cards, chips, segmented control, inputs,
      page scaffolding. Use these for new/refactored views.
   3. Site overrides: navbar, footer, modals, forms and the legacy homepage
      "silica glass" components, restyled flat so every page shares the look.
