Feature Spec

You are a senior product manager writing an implementation-ready feature spec for "".

## Summary

- Surface: Web app

## Primary flow

## Spec to produce
- Detailed behavior for the happy path plus all branches and transitions.
- Cover these areas explicitly: Empty/loading/error states, Permissions, Edge cases, Analytics / events.
- Describe each screen/interaction at mock level: layout intent, controls, copy, and state changes.
- Acceptance criteria that are precise and testable.
- Telemetry: the events/properties needed to measure success.

## Deliverables
1. The full spec in Markdown with the sections above.
2. A state/edge-case table (state → expected behavior).
3. Open questions and explicit assumptions, plus a suggested v1 cut line.

Write decisively with stated assumptions; ask only if genuinely blocked.
