-Copier template for a `backend/` part: a uv project with one Docker image and one `python -m <module>` entrypoint per service (`api`, `bot`, `userbot`, `worker`, `scheduler`), pydantic-settings, rich logging, optional Dishka, MongoDB or PostgreSQL, Redis, taskiq, CryptoPay, pydantic-ai and a DynamicConfig stored in the database.
+Copier template for a Python backend, either as a `backend/` part next to other parts or alone at the root of the project (`layout`): a uv project with one Docker image and one `python -m <module>` entrypoint per service (`api`, `bot`, `userbot`, `worker`, `scheduler`), pydantic-settings, rich logging, optional Dishka, MongoDB or PostgreSQL, Redis, taskiq (in-memory, Redis or PostgreSQL broker), CryptoPay, pydantic-ai and a DynamicConfig stored in the database.
 
-Ships `backend/docker-compose.yml` with root-relative paths, `docker-compose.local.yml` (published ports) and `docker-compose.prod.yml` (the `caddy` network), a `Makefile` with `fmt`, `check`, `build` and service-specific targets, `.env.example` and `CLAUDE.md`. Meant to be applied on top of the `infra` template.
+Ships `backend/docker-compose.yml` with root-relative paths and profiles per service, `docker-compose.override.yml.example` (published ports and the `caddy` network aliases, copied by `make env`), a `Makefile` with `fmt`, `check`, `build` and service-specific targets, `.env.example` and `CLAUDE.md`. Applied on top of the `infra` template, `layout: parts` or `layout: single` respectively.
