- Add bible/ with 7 hierarchical English-only files covering overview,
architecture, database schemas, API endpoints, config/env, backup, and dev guides
- Consolidate all docs from README.md, CLAUDE.md, man/backup.md into bible/
- Simplify CLAUDE.md to a single rule: read and respect the bible
- Simplify README.md to a brief intro with links to bible/
- Remove man/backup.md and pricelists_window.md (content migrated or obsolete)
- Fix API docs: add missing endpoints (preview-article, sync/repair),
correct DELETE /api/projects/:uuid semantics (variant soft-delete only)
- Add Soft Deletes section to architecture doc (is_active pattern)
