Strategic pivot: the dropout-fill rescue, the anime-seg fill backend, the
BiRefNet+anime-seg intersection, and the recolor pass all existed to repair
source images whose hair was already green-contaminated or broken at generation
time. Fixing the source instead (clean pastel-background generation) makes the
matte high-contrast, so that whole compensation layer is unnecessary. Remove it.
- Two pipelines via segmentation.enabled:
false -> chroma-only (Chroma + ViTMatte)
true -> single segmenter (default anime-seg, switchable birefnet) -> trimap
then ViTMatte refines, pymatting estimates foreground, despill cleans spill.
- Generalise the green-hardcoded colour logic to a screen_color prior (hex, e.g.
"#CFEFFF"; default null = green auto-detect, byte-identical). chroma keys off
Lab/RGB distance to the colour; despill removes chroma along its Lab direction.
Added --screen-color CLI flag.
- Removed dead code: fill_seg_dropouts + seg_fill*/intersection params,
SegmentationSettings.fill_backend/fill_model_name/sharpen, unsharp_mask,
recolor.py + RecolorSettings.
