// ── Color space definition ─────────────────────────────────────────
// Helmlab MetricSpace is the perceptual forward space behind `deltaEHelmlab`.
// Its coordinate system is shaped to maximize ΔE prediction accuracy on
// visual-difference datasets (COMBVD: BFD-P, Witt 1999, RIT-DuPont, Leeds),
// not author convenience. As a result:
//   - the ab plane is asymmetric (the metric was fit to directionally
//     asymmetric human discrimination thresholds);
//   - the L axis exceeds 1 for highly chromatic colors because the
//     Helmholtz–Kohlrausch boost is modeled explicitly (high-chroma colors
//     appear brighter than equiluminant neutrals);
//   - the achromatic axis is not pinned to (0, 0) — the gray axis sits
//     slightly off-origin in this coordinate system. Distance is
//     translation-invariant, so this does not affect ΔE quality.
//
// For CSS-author-facing color authoring (palettes, gradients, gamut
// mapping), use HelmGen (`helmgen`) instead. This space (`helmlab-metric`)
// is exposed primarily so the metric forward is inspectable for
// debugging, color-science exploration, and as the internal forward used
// by `deltaEHelmlab`.

/**
 * Helmlab GenSpace — generation-optimized color space for interpolation.
 *
 * Pipeline (v0.11.1, depressed cubic + chroma power + L-gated enrichment):
 *   XYZ → M1 → depcubic(α=0.021) → M2 → chroma_power(0.978) →
 *   PW_L → L-gated hue enrichment → Lab
 *
 * Optimized for perceptually uniform gradients, palette generation,
 * and color-mix. 59-8 vs OKLab in head-to-head benchmarks (83 metrics,
 * 3038 gradient pairs, sRGB/P3/Rec.2020). 360/360/360 cusps.
 *
 * Key properties:
 *   - Depressed cubic: y³ + αy = x, finite derivative at zero
 *   - Chroma power (0.978): improves gradient CV uniformity
 *   - L-gated hue enrichment: fixes blue→white purple shift
 *   - Structurally achromatic: a=b≈0 for all grays
 *
 * Note on blue-region gamut fold:
 *   All M1→f→M2 spaces (OKLab, IPT, HelmGen) exhibit a tiny non-contiguous
 *   gamut region near h≈260° in sRGB. This is a mathematical consequence of
 *   mixing LMS channels before applying a power-like transfer: the inverse
 *   creates a cubic polynomial that can have two positive roots in the blue
 *   region. OKLab has 46 such holes; HelmGen has 5, each ~0.001 chroma wide
 *   (sub-pixel, invisible). See: color.js#81, csswg-drafts#7071.
 *
 * Reference: arXiv:2602.23010
