/* /10things: a ranked countdown ending at 0 (the price). Backgrounds cycle through the three brand colours.

   view timelines show static screenshots. Contrast: --muted 6.1:1 and --terra-deep 5.0:1 on cream for small text; the terracotta panels use
   --terra-deep so white body copy reads at 5.6:1. */
