- Simplified `components/login-modal.html` to center the QR code and use a "Copy Link" button instead of a large textarea.
- Updated `js/ui/loginModalController.js` to support the new DOM structure and error handling.
- Added `docs/nip46-roadmap.md` to document current state and future features.
- Fixed `NostrClient.destroy()` usage (synchronous void method) in `js/nostr/client.js`.
- Relaxed NIP-46 `connect` response validation in `js/nostr/client.js` and `js/nostr/nip46Client.js` to accept "ack" (case-insensitive) as a valid success signal, preventing timeouts with signers that do not echo the secret.
