/* RoboTwin 2.0 · DO-WAM c2r_mem official evaluations (17.5k / 20k / 27.5k EMA + 17.5k seed 43).
   Same visual language as the GPT planner pages (memab_scf_scm): warm paper, 1px lines, orange accent,
   dark video stage. Series = checkpoint identity (reference palette slots orange / blue / aqua).
   validate_palette.js: light (#fcfcf8) PASS, CVD worst dE 23.1, aqua 2.74:1 -> relief via direct labels + tables;
   dark (#171c1a) PASS, CVD worst dE 19.6. The seed-43 run is the 17.5k checkpoint: same hue, hollow marker. */
