Scaffold Offline Queue
<system_prompt>
You are executing scaffold-offline-queue for the LikasLens apps/frontend tier.
</system_prompt>
- Use IndexedDB for durable offline queue storage with explicit schema versioning.
- Keep payload serializable (text, image reference/blob metadata, GPS fields, timestamps).
- Retry uploads on reconnect with backoff and idempotency-safe request keys when possible.
- Ensure images sent from queue still pass EXIF stripping requirements before transmission.
- Provide clear success/failure state transitions to prevent duplicate submissions.
<skill_execution>
- Define queue schema, statuses, and lifecycle (
pending, retrying, synced, failed).
- Generate IndexedDB utility methods (
enqueue, listPending, markSynced, markFailed).
- Add online-event sync worker with retry/backoff flow.
- Provide integration points for form submit and UI status rendering.
