Skip intervention gracefully for incompatible latent formats (LTXAV)
...
LTXAV uses a flattened 1D latent layout (e.g. [1, 1, 466048]) where
spatial H/W < 2, making 2x2 patchification impossible. patchify() now
returns None for such formats, and all hooks skip intervention cleanly.

Support 5D video VAE latents (Wan) in patchify/unpatchify
...
Video VAEs output [B, C, T, H, W]. Patchify now merges T into batch,
processes all frames, and unpatchify restores the 5D shape.
Updated all callers to pass extra_shape through.

Implement LCS plugin for training-free color control in FLUX
...
Implements "The Latent Color Subspace" (arXiv:2603.12261v1, ICML 2026)
as a ComfyUI plugin with V3 API + V2 backward compatibility.
6 nodes across 3 categories:
- LCS/calibration: LCSCalibrate (PCA from VAE), LCSLoadData (cache load)
- LCS/intervention: LCSColorIntervene (single color), LCSColorBatch (multi)
- LCS/observe: LCSPreviewColors (latent color map), LCSStepObserver
Core modules: patchify (16ch->64d patches), bicone HSL<->LCS mapping,
alpha_t/beta_t tables (51 entries from Appendix F), PCA calibration,
and timestep normalization with residual preservation.
