/* Compound explorer — shared by /vendors/<slug> and /dashboard/vendors/<id>.
   Every --vp-* token carries a fallback so the component renders correctly
   outside the public vendor page's palette (the dashboard uses --accent /
   --txt / --bord). Palette itself is validated: sequential amber ramp for
   magnitude, diverging red/blue for dose. */
    /* ── Compound explorer ────────────────────────────────────────────────────
       Palette is VALIDATED, not chosen by eye (dataviz skill):
         sequential amber ramp  #6b4a12 → #F0B544  — monotone L, single hue,
           light end 2.30:1 on the #101418 panel
         diverging dose poles   #E4644C under ↔ #3987e5 over, neutral #383835
           — ΔE 22.7 protan / 30.6 normal, all six checks pass
       Sequential for magnitude (purity, cert count); diverging ONLY for dose,
       the one metric with a meaningful zero. */
