Wire BiRefNet into the pipeline (lazy-loaded) and build the trimap from the semantic subject mask refined by the green key, used when segmentation is enabled. generate_trimap (chroma-only) stays as the no-segmentation fallback. Authority split: the mask decides subject topology (keeps green-tinted hair as foreground, drops see-through holes), the bright-green key sharpens the screen boundary, ViTMatte refines a small protective band. Background follows the mask directly so interior holes survive; the band is small so it does not swallow finger gaps. End-to-end on the samples: green hair preserved, finger-gap green 99% transparent (BiRefNet marks it background; was 100% foreground before), leg edges smooth -- topology/colour/edge problems local cues could not solve, with no hard alpha surgery. - SegmentationSettings wired into PipelineSettings/config; --device propagates. - TrimapSettings: seg_core_threshold, seg_loose_threshold. - New debug output seg_mask.png.
