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.
