   Smart Pantry — single mobile-first responsive stylesheet.

   Sections:
     1. Theme tokens (CSS variables; light + dark)
     2. Base / resets / typography
     3. App shell: header, sidebar (>=768px), bottom tab bar (<768px)
     4. Views (generic helpers used by feature views)
     5. UI kit (.ui-*): card, button, field, modal/sheet, spinner, badge, pill, toast
     6. Settings view specifics
     7. Safe-area insets + responsive breakpoints
   The breakpoint between "phone" (bottom tabs) and "desktop website" (sidebar) is
   768px. Everything is mobile-first; the wide layout is layered on at the media query.
