docker — compose scratch pad

Includes b use/ with a stub docker-compose.yml and web-ui/ assets.

Populate docker-compose.yml with actual services (services: block) referencing your images or build contexts inside web-ui/.

Suggested workflow:

cd "b use"
docker compose config   # validates structure once filled
docker compose up -d    # once services exist

Add per-service README files under child directories once they stabilize.
