- New InstallSheet mounted in the root layout: appears ~1s after load on
iOS/Android phones and tablets, over any screen including the key gate,
with a dimmed backdrop. Never on desktop, never in standalone mode, and
at most once per 7 days after a dismissal (localStorage).
- Platform/browser detection (lib/install.ts): iPhone/iPad incl. iPadOS
reporting as Mac with touch, Android, Safari vs Chrome vs other vs
in-app browsers, with step 1 adapted accordingly.
- iOS: numbered steps with chips (Safari, Share, ... , More, Add to Home
Screen) and the accent Add pill. Android: captured beforeinstallprompt
turns into a native Install button; fallback steps use Install app /
Add to Home screen chips and an accent Install pill.
- Close via X, backdrop, Escape or swipe-down on the handle; the site is
untouched afterwards. Anchored to 100dvh so browser toolbars never hide
the last step; pb-safe respects the home indicator.
- Dark sheet by default; light only when the app theme was explicitly set
to light. Settings gains a mobile-only Install app row that reopens it.
- The inline head script captures beforeinstallprompt before hydration and
records appinstalled. Old InstallHint banner removed.
- Tests: new install-sheet suite (45 checks across iPhone Safari/Chrome/
in-app, Android Chrome/Samsung, desktop, prompt path, dismissal, 7-day
expiry, standalone, Settings row, both themes); pwa suite updated.
