/* Mueller performance dashboard.
   Palette: series hues are the dataviz reference DARK set, validated with
   scripts/validate_palette.js (lightness band, chroma floor, CVD separation,
   normal-vision floor, contrast — all PASS on a dark surface).
   Mueller gold FAILS as a series colour (L 0.70 outside band, chroma 0.075
   below floor) so it is a brand/UI accent only, never a data mark. */
