/* Kank Pledge: radiant gold, black and white. Black surfaces (page, header, glossy black cards, tab bar), crisp white
   text, and a radiant metallic gold (deep amber to a pale champagne shine, never flat yellow) only where it counts:
   the Kank logo, money amounts, the gold rule, primary buttons, secondary buttons and the progress bar, on a plain black page. Only gold, black, white and red
   (failures); nothing else.
   Mobile first, system fonts; animations only move or fade small layers and stop under reduced motion.
   Contrast (checked by npm test), measured at the lightest point of a glossy black card (#1C1C1C): white 17:1,
   grey 13.6:1, small gold text 8.8:1, amounts 6.4:1; black on gold buttons >= 5:1. */
