-- `main/domain/{include,internal,src}`: business-domain services.
-- `main/control_plane/{include,internal,src}`: lifecycle, policy, health, retry/backoff orchestration.
-- `main/app_composition/{include,internal,src}`: composition boundary; `app_main` only wires modules.

+- Use 4-space indentation and keep braces/function style consistent with existing `components/*/*.c`.
 - Prefer `lower_snake_case` for functions and variables; use module-prefixed public APIs.
 - Use `UPPER_SNAKE_CASE` for macros/constants (`CMD_SEND_DATA`, `WIFI_CONNECTED_BIT`).
 - Prefix file-local statics with `s_` (for example `s_server`, `s_jobs`) and keep per-file `TAG` logging constants.
