/* NATURE ONE 2026 — Lineup Explorer
   ---------------------------------------------------------------
   Direction: an operations board for a night on a decommissioned
   missile base. Chrome is achromatic on purpose — the six genre
   hues are the only colour that carries meaning anywhere in the UI.
   Palette validated with dataviz/scripts/validate_palette.js in
   both modes (light warns sub-3:1 on 3 slots → genre always ships
   with its text label, never colour alone).
