"""Kit extraction / generation workflow (mostly legacy; headless-first).

This module extracts “kit-like” assets from an installation/module so they can be consumed by
the Holocron indoor pipeline (MDL/MDX/WOK + textures/lightmaps + door/placeable walkmeshes).

Important project direction:
- On-disk “kits” are increasingly **deprecated** in favor of implicit `ModuleKit` workflows.
- This module remains useful for interoperability/export, and for reproducing older toolchains.

Qt note:
- This module *may* use Qt for image generation if available, but must not require it.
- If Qt is unavailable, it falls back to Pillow.
