After:

Additional Notes:

Added backend/API documentation in docs/backend/backend_python/api.md.
The documentation includes:

A high-level FastAPI backend architecture diagram using Mermaid.
A concrete GET /images/ request/response flow.
Short explanations of the interaction between the FastAPI router, route handler, database layer, utility layer, and Pydantic response models.

The scope is limited to the Backend/API documentation as requested. No backend implementation, README, Rust/Processing documentation, Architecture page, or MkDocs navigation changes were made.

Validation performed:

python -m mkdocs build --strict passed successfully.
git diff --check passed successfully.

Changes

Python backend documentation

Layer / File(s)	Summary
Backend architecture overview `docs/backend/backend_python/api.md`	Documents FastAPI routing, route handlers, database and utility layers, SQLite persistence, and Pydantic JSON responses.
Image listing request flow `docs/backend/backend_python/api.md`	Documents the `GET /images/` flow from routing and `get_all_images` through tagged database retrieval, metadata parsing, and response model conversion.

Poem

A rabbit maps the backend trail,
With diagrams bright and details clear.
GET /images/ hops through each step,
From SQLite to responses near.
FastAPI guides the way.
