# Reusable preview inputs

`head_portrait_01.png` is the shared source for head and face effects. It is an
AI-generated adult studio portrait with a frontal face, open eyes, visible ears,
a neutral expression and space above the hair for horns, halos and stickers.
It contains no effect. The built-in image_gen tool created the image; its exact
generation prompt is retained in `profiles.json`.

`profiles.json` and `tools/preview_input_profiles.py` provide the shared selection
contract for preview generators. Explicit head/face assignments take precedence.
Face-only algorithm packages also select this portrait. Packages using skeleton,
matting or avatar body algorithms use the new dark-background full-body photo.
Add exceptions to `head_face_ids` after checking their
authored composition; face detection alone does not make a body effect a head
effect.

`tools/review_body_effects.py` records the selected profile, source path and SHA256
in every render signature and audit. Changing the source invalidates cached
media. Existing previews keep their actual source provenance until replaced.
`tools/check_body_scene_profiles.py` reuses that recorded source for regressions.
Each effect still retains one MP4 and one poster. User-rejected effects remain
unresolved even when the new input renders successfully.

`full_body_dark_01.png` is a second reusable adult full-body source, created
with the built-in image_gen tool. Its dark slate-purple background keeps
additive wings, lightning and particles visible. It contains no VFX. The exact
prompt, size and SHA256 are recorded in `profiles.json`. It is the default
body input for the expanded HF catalog; old captures retain their provenance.
Head-only effects continue to use the head portrait. A labelled horizontal pan
of the same photo exercises frame-history effects such as Infinite Echo; it
does not synthesize poses or algorithm results.
