- Segmentation backend now defaults to birefnet (ZhengPeng7/BiRefNet); anime-seg is selected at runtime with --seg-backend anime-seg, which also swaps in the matching weights (unknown backends raise). Config files stay for detailed tuning, not backend selection. - Default device is now cpu everywhere (dataclass defaults, default.yaml, birefnet.yaml); pass --device cuda for GPU. Avoids a hard CUDA-required failure on machines without a CUDA-enabled PyTorch build. - Docs: README + workflow status note updated (backend via --seg-backend, CPU default, examples no longer force --device cuda).

# Same as default.yaml but with the BiRefNet segmentation backend instead of
|
|
# anime-seg. BiRefNet is a general salient-object segmenter (not anime-specific),
|
|
# so it can find subjects anime-seg misses. It ships custom modelling code, so it
|
|
# needs trust_remote_code (handled in code) plus timm / einops / kornia, and the
|
|
# first run downloads weights from HuggingFace (set HF_ENDPOINT behind a firewall).
