Triton + SageAttention (ComfyUI acceleration)

See also comfyui-launch-flags for the full attention / VRAM / cache flag matrix. Note the Z-Image exception: Z-Image is broken under --use-sage-attention, so launch it with --use-pytorch-cross-attention instead.

Prefer kitchen INT8 attention when it is available

If kitchen action:"status" (or panel_kitchen) reports kitchen present and int8_attention_is_available on this GPU, launch with --use-ck-attention and skip the sageattention wheel dance. Kitchen INT8 attention is a ComfyUI flag; it does not need a version-matched sageattention wheel. Restart required, consent-gated like every restart.

Only fall through to the Triton + SageAttention install below when kitchen INT8 is unknown or not available. A failed kitchen probe is unknown, not a no.
