/* V-day. Brand tokens come from /_brand/brand.css; this file only adds the
   series colours and the layout for this page.

   Series colours, validated with the dataviz skill's validate_palette.js on
   black: ETC is brand green, the hero series. ETH #8c84d6 muted violet
   (6.3:1), ETHW #c27f50 muted amber (7.0:1). Worst pair dE 19.9 under
   protanopia. Identity never rests on hue alone: legend, direct labels and
   dash patterns carry it too. */
