/* The interactive charts of docs/project/performance.md (drawn by perf.js from results.json).
   Colors are tokens, redefined for Material's dark (slate) scheme; the categorical slots are a
   validated colorblind-safe order (adjacent pairs clear a CVD delta E of 8 in both schemes, and a
   normal-vision delta E of 15). Three light-mode slots sit under 3:1 against the surface, so every
   series also carries a legend entry, a marker shape, a direct label and a table row: color never
   carries identity alone. */
