Route faint hair (BiRefNet M 0.08-0.15) into the unknown band instead of sure background, giving ViTMatte a chance at it. On its own this does not recover the green-contaminated shoulder wisps: those are ~pure green (dominance +0.88, like the screen) so ViTMatte cuts them regardless of trimap -- that is handled by the upcoming segmentation dropout-fill. The finger gap (M~0.02) stays sure background. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
