/* =====================================================================
   responsive.css — Globalised mobile-responsive standards.

   ONE place to tune the mobile system.  Linked on every page so any
   change here propagates everywhere.  Per-page CSS files should prefer
   these utilities (.r-stack, .r-grid, .r-table, .r-sheet, .r-toolbar)
   instead of redefining their own mobile rules.

   Conventions:
     - Breakpoints: --bp-mobile (768px), --bp-small (480px), --bp-tiny (380px)
     - Tap targets: --tap-min (36px), --tap-comfort (40px), --tap-primary (44px)
     - Use dvh for full-viewport heights (iOS Safari address bar safe).
     - Use env(safe-area-inset-*) for fixed/floating elements.
