"""DockerBottleBackend — the Docker implementation of BottleBackend.

This module is a thin façade. The real work lives in three siblings:

  - prepare.py  — host-side resolution into a DockerBottlePlan
  - launch.py   — bring-up + teardown context manager
  - cleanup.py  — orphan enumeration, removal, and active listing

The base class's `prepare` template runs cross-backend host-side
validation before calling `_resolve_plan` here.
