C4 Level 2 + Level 3 system decomposition. Per container: technology, purpose, responsibilities, APIs exposed + consumed, data stores, deployment, scaling, tenant model, ownership. Per container relationship: protocol + purpose + synchronicity + failure mode + rate. L3 scopes to one container with typed components (controller / service / repository / adapter). Avoids L4 code details. Mermaid diagrams with optional PNG export.
