## 1. Implementation
- [ ] Add DB support for bookmark ordering (migration + init schema)
- [ ] Expose bookmark ordering in DTOs and OpenAPI schema
- [ ] Add API endpoint to reorder bookmarks within the same folder
- [ ] Ensure list endpoints return folders/bookmarks in stable order (parent+sortOrder, etc.)
- [ ] Implement touch-friendly drag sorting in Web UI for folders and bookmarks
- [ ] Treat root group (folderId null) as a first-class group for display and bookmark reorder
- [ ] Add basic verification steps (build + manual smoke checklist)

## 2. Spec Updates
- [ ] Update OpenAPI contract for bookmark sortOrder and reorder endpoint
- [ ] Update OpenSpec API capability delta requirements
