Two device-level issues cost real debugging time and neither is an app bug:
- adb could not open the phone: Ubuntu's udev rules match vendor AND
product, and list only older TCL products, so nothing matched 1bbb:0c01.
- A blank grey window: TCL's AppBootManagerService refuses to let the app
bind the WebView renderer service while the display is dozing, so the
page never parses. No crash, no JS error, empty document.title, and the
failure is sticky for the process lifetime.

Wraps reference/sp404-layers as a sideloadable APK without editing the
reference, which stays the frozen spec for the Phase 2 React port.
- sync-www.sh builds www/ from reference/ + native/, asserting each patch
anchor so a reference change fails loudly rather than shipping broken
- drops the service worker (would serve a stale app after an APK update)
- haptics via a navigator.vibrate override, so buzz() needs no change
- localStorage mirrored into Preferences; sync load()/save() untouched
- hardware back: sheet -> Explore tab -> exit
- edge-to-edge handled in MainActivity: Android 16 + targetSdk 36 removes
the opt-out, and a WebView never fills env(safe-area-inset-*), so insets
are pushed into CSS custom properties instead
