/* ── Fair Flow Check — Material 3 design tokens ──────────────────────────
   Reference palettes are generated in OKLCH from a violet brand seed
   (hue 293, matching the product's original indigo/lavender identity) plus
   a rose tertiary and two extended semantic hues (success green, warning
   amber) in the same style Material Theme Builder produces for custom
   colors. Role tokens below map these tones to M3 system roles for light
   and dark schemes. See https://m3.material.io/styles/color/roles. */
