Fix iOS PWA full-screen layout (black bars + safe-area bleed)#89
Merged
Conversation
iOS standalone PWAs resolve `100vh`/`height:100%` inconsistently — they can return the safe viewport (innerHeight, ~894px) instead of the full screen (~956px), leaving a black letterbox bar and pushing chrome under the notch / home indicator. Pin #root with `position: fixed; inset: 0` (with a 100dvh fallback) so the shell always anchors to the full layout viewport — the entire screen under viewport-fit=cover — and switch the app/auth/login/admin roots from h-screen/w-screen to h-full/w-full so they inherit that reliable size. Existing pt-safe / pb-safe padding then keeps chrome clear of the unsafe zones without double-counting.
