- CrewCard: rebuilt to fit any screen width — clip overflow, truncate name/location, single wrapping badge row, consistent avatar sizing; responsive header - Amber web login: after opening Amber, drop user on manual paste step after 2.5s so the spinner never hangs when the callback opens in a new tab or clipboard is blocked; keep polling on the paste step so a late callback still auto-completes - Stash: hasNip44/hasNip04 now fall back to the active login when pubkey matching fails, so logged-in nsec/amber users are no longer wrongly told "Encryption Required" - Signup: added an explicit welcome step that explains account creation and only generates the keypair when the user taps "Create my account" (no more silent auto-creation on dialog open) Co-authored-by: shakespeare.diy <assistant@shakespeare.diy>

/**
|
|
* signerCapabilities — safely probe what a Nostr signer can do.
|
|
* ─────────────────────────────────────────────────────────────────────────────
|
|
* The NUser extension signer exposes `.nip44` / `.nip04` as GETTERS that call
|
|
* `.nostr` (window.nostr) and THROW "Browser extension not available" when the
|
|
* extension isn't present. Accessing `user.signer?.nip44` during render will
|
|
* therefore crash the whole React tree for extension logins whose extension
|
|
* isn't injected yet (page-load race) or is missing entirely.
|
|
*
|
|
* These helpers determine capability WITHOUT touching the throwing getter:
|
|
* we look at the login type + probe `window.nostr` directly (a plain property
|
|
* read that never throws). Use `hasNip44(user, logins)` anywhere you'd
|
|
* otherwise write `!!user?.signer?.nip44` in a render path.
