/* ==========================================================================
   HomeRP app shell (#105) — mobile-first
   ==========================================================================

   The signed-in chrome, authored from the phone outwards. The phone layout is the
   primary one; the desktop layout is the phone layout plus a persistent sidebar and
   denser spacing.

   What 0.3.0 did, and why this replaces it:

   - The only navigation was a 258px off-canvas drawer — 69% of a 375px viewport —
     opened by a 34x34 burger in the top-left corner, out of thumb reach and below
     the 44px tap-target minimum.
   - There was no `dvh`, no `env(safe-area-inset-*)` and `index.html` had no
     `viewport-fit=cover`, so the sticky top bar and the fixed drawer ran under the
     notch and the iOS home indicator.
   - The declared breakpoint was 768px, which put a tablet in the desktop layout
     with a 258px sidebar on a 768px screen.

   Now: five primary destinations in a bottom tab bar in thumb reach (< 1024px), a
   52px top bar, bottom sheets for everything secondary, and the sidebar only from
   1024px up. The drawer, the burger, its checkbox and its scrim are gone.

   One rule throughout: no colour, radius, spacing or type literal — tokens only.
