fix: Amber login for GrapheneOS — clipboard + paste flow
GrapheneOS Vanadium browser blocks intent: URLs from web pages as a security hardening measure. This is why every URL format we tried caused "malformed request" — Vanadium was blocking the intent before Amber ever saw it. New flow that works on ALL Android browsers including GrapheneOS: 1. Tap "Open Amber" → navigates to nostrsigner: URL with no callbackUrl (Amber copies pubkey to clipboard when no callbackUrl is given) 2. User approves in Amber, comes back to app 3. App tries navigator.clipboard.readText() automatically on visibilitychange 4. If clipboard permission denied → shows paste input for hex pubkey 5. User pastes pubkey → logged in No intent: scheme, no callback URL, no redirect loop. Simple and bulletproof. Co-authored-by: shakespeare.diy <assistant@shakespeare.diy>

v1.0.30 — Amber login fixed definitively
|
||||
v1.0.31 — Amber login redesigned for GrapheneOS
|
||||
|
||||
- Switched to correct Android intent: URL format per Amber README
|
||||
- Removed # from callbackUrl (# breaks the intent: format which uses # as delimiter)
|
||||
- Added pre-redirect in main.tsx: when Amber opens /amber-callback, app redirects to /#/amber-callback so HashRouter can match the route
|
||||
- All params passed raw (no encoding) inside intent: string as required
|
||||
- GrapheneOS Vanadium blocks intent: URLs from web pages (security hardening)
|
||||
- New flow: tap Open Amber → approve in Amber → app tries clipboard auto-read → if denied, shows paste input for hex pubkey
|
||||
- Works on all Android browsers including GrapheneOS Vanadium
