/* =============================================================
   mobile.css — Evermail WebApp responsive overrides
   Breakpoint: ≤768px = mobile. Tablet (769–1024) keeps desktop layout.
   Load this LAST so its @media rules win by cascade order.

   Tokens this file depends on (defined in colors_and_type.css):
     --backdrop-color, --backdrop-color-strong
     --sheet-radius, --sheet-shadow, --sheet-handle-color
     --ease-spring, --ease-soft-out
     --duration-sheet, --duration-tab-indicator

   Reusable primitives used here live in ui_kits/airy.css:
     .bottom-sheet, .pill-subnav, .viewer-mobilebar, .tab-indicator
   New mobile UIs should prefer those primitives over bespoke rules.
