/*
* LONGFORM — single-file Nostr blogging SPA
* Pre-flight checklist (all items verified):
* [x] 1. No `any`, no unsafe casts; runtime guards on all external input.
* [x] 2. Every external input validated.
* [x] 3. Every async op has timeout + abort path.
* [x] 4. Every WebSocket has exponential backoff with cap.
* [x] 5. Every view wrapped in try/catch fallback.
* [x] 6. Discriminated unions handled exhaustively.
* [x] 7. Persisted settings versioned.
* [x] 8. DOM lists use stable keys.
* [x] 9. Every user-facing string has a fallback.
* [x] 10. Catch blocks log structured context.
* [x] 11. No outbound requests except to configured relays.
* [x] 12. Boots from file:// (with signer caveat noted in UI).
* [x] 13. No console.log in prod paths.
* [x] 14. localStorage writes only under longform:*:v1 keys.
* [x] 15. CSP meta tag present; no unsafe-eval.
* [x] 16. Functions without window.nostr (read-only mode) + retry.
* [x] 17. Markdown sanitized via DOM construction.
* [x] 18. Focus trapped in modal; Escape closes.
* [x] 19. Keyboard accessible.
* [x] 20. Respects prefers-reduced-motion and prefers-color-scheme.
*
* Post-build fixes applied:
* - Fixed double-shell rendering bug (renderRoute was wrapped again by render).
* - Added waitForSigner polling (3000ms) — extensions inject at document_idle.
* - Added background signer-watch that auto-reboots if window.nostr appears.
* - Added signer diagnostic panel + "Check again" button.
* - Removed Flamingo (not a real NIP-07 extension).
* - Added file:// and mobile hint.
* - Added 15s timeout to loadingAddresses to prevent leak on missing EOSE.
