-/**
- * Custom MainActivity that lets the WebView hand OFF `intent:` / `nostrsigner:`
- * URLs to the Android OS so Amber's approval screen actually opens.
- *
- * WHY THIS EXISTS
- * ───────────────
- * When the JS signer navigates to an `intent:...;scheme=nostrsigner;...;end`
- * URL, Capacitor's default WebView treats it as a page navigation and silently
- * DROPS it — so Amber never launches and every signing action (delete, accept
- * crew invite, zap, profile edit) hangs forever. Login works only because it
- * goes through the native plugin's startActivityForResult; JS-initiated intents
- * were never reaching the OS. On GrapheneOS this is enforced strictly.
- *
- * The fix: override shouldOverrideUrlLoading. Whenever the WebView tries to load
- * an `intent:` or `nostrsigner:` URL, we parse it and call startActivity()
- * ourselves — a REAL native launch that opens Amber, exactly like login. The
- * result comes back via the app's custom-scheme deep link
- * (org.skatespots.app://amber-callback...), handled by DeepLinkHandler /
- * resolveAmberIntent in the web layer.
- *
- * This file is injected into the generated android/ project at build time by
- * scripts/inject-main-activity.mjs (android/ is not committed).

+v1.2.10
+
+🛠️ Fixes a startup crash (black screen) introduced in the previous build and
+keeps the Amber signing fix: signing now opens Amber the same reliable way
+login does, so delete / accept invite / zap complete instead of hanging.
+
+After updating, log OUT and log back IN once.

 v1.2.8
 
 🛠️ Amber finally pops up — signing works (the real fix)
