C4 Model

The architecture is documented using the C4 model, which provides successive levels of zoom into the system.

Level	Page	Audience
1 – System Context	Context	Anyone — what the system does and who uses it
2 – Containers	Containers	Architects, leads — the deployable units and how they communicate
3 – Components	Components	Developers — the internal structure of each container

Diagrams are written in Mermaid C4 syntax.
