cityImage module ownership map

This file records the current post-refactor ownership boundary.

Status meanings:

• keep: cityImage owns the semantics.

• keep thin: cityImage owns the boundary/output semantics but delegates algorithms, acquisition, or file IO.

• keep small: small helper module retained because multiple owned modules need it.

Module	Owner	Status	Optional deps	Delegates to	Keep reason
cityImage/__init__.py	public API	keep	none	lazy import map	Top-level import contract and curated public surface.
