## Summary
Backport of #6139 to `rh-test` branch.
Added Service Worker to inject Firebase auth headers into browser-native
`/api/view` requests (img, video, audio tags) for cloud distribution.
## Changes
- **What**: Implemented [Service
Worker](https://developer.mozilla.org/en-US/docs/Web/API/Service_Worker_API)
to intercept and authenticate media requests that cannot natively send
custom headers
- **Dependencies**: None (uses native Service Worker API)
## Implementation Details
**Tree-shaking**: Uses compile-time `isCloud` constant - completely
removed from localhost/desktop builds (verified via bundle analysis).
**Caching**: 50-minute auth header cache with automatic invalidation on
login/logout to prevent redundant token fetches.
## Backport Notes
- Resolved merge conflict in `src/main.ts` where remote config loading
logic was added on `rh-test`
- Preserved the CRITICAL comment about loading remote config first
- All files from original commit included
- Typecheck passed successfully
