Magnus Hedemark abfd1dd5e1 feat: fortify color-management skill — 10 phases ...

Phase 1 — CIEDE2000/CIE94/CMC in color-difference.py with colour-science
  fallback and pure Python implementations
Phase 2 — Soft proofing workflow reference (NULL Curves, 4 strategies,
  LCMS2 linear gamma bug, gamut check automation)
Phase 3 — Monitor calibration workflow (ArgyllCMS dispcal/dispread/colprof,
  DisplayCAL GUI guide, colorimeter correction matrices)
Phase 4 — dcraw pipeline reference (raw → linear TIFF → profile assign →
  working space convert, negative tristimulus problem)
Phase 5 — Hex quantization reference (prequantized primaries methodology,
  which profiles affected, ArgyllCMS prequantization)
Phase 6 — GIMP LCH layer stack template (3-group architecture, Chroma mask,
  Luminance desaturation, out-of-gamut monitoring)
Phase 7 — Working space decision tree (trigger-based flow, quick reference
  table, why-choose guides for common spaces)
Phase 8 — Concrete failure gotchas (gamma slider + unbounded sRGB = magenta,
  wrong-working-space color correction, channel-mixing out of gamut)
Phase 9 — Unified color-report.py (combines inspect + well-behaved +
  gamut check into single report)
Phase R — DisplayCAL research incorporated into monitor calibration reference
