11-task plan (T0-T10) covering the sibling docker-env2/ directory: SQL setup script + mount, Traefik config, central/site appsettings, docker-compose, lifecycle scripts, .gitignore, READMEs and cross-refs, verification checklist, and a manual smoke test. No application code changes -- pure deploy tooling. Most tasks (T0-T9) are independent and parallel-ready; T5 is gated on T0 + T4; T10 gates on all of T0-T9.
