/* =============================================================================
   Family Assistant — UI layer
   -----------------------------------------------------------------------------
   A small, hand-rolled design system layered on top of Bootstrap 5.
   No build step. Everything is driven by CSS custom properties so the whole
   app can be re-themed (including automatic dark mode) from one place.

   Sections
     1. Tokens (colour, radius, shadow, spacing)
     2. Dark mode
     3. Base / typography
     4. App shell (top bar, desktop nav, bottom nav)
     5. Surfaces (cards, tiles, tables)
     6. Controls (buttons, chips, forms, alerts, modals)
     7. Page furniture (page header, filters, empty states, FAB)
     8. Feature-specific (feed, calendar, review)
     9. Utilities, motion & accessibility
