build-container / build (push) Successful in 7m39s
- Store tab with sections; the book store, LibriVox and radio finder are shown inside it (old entry points redirect) - My Store: admin uploads files or copies from Seafile; books go to a person's shelf, music plays in the player, apps download - Extensions: one HTML file run in a sandboxed frame with a small storage/toast/user bridge; example in docs/extensions Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
