 * A warm off-white ground instead of cool grey, one vermilion accent, and
 * nothing else. Hairline rules replace cards and shadows; every numeral is
 * tabular so figures never jitter as they count. The temperature lives in the
 * neutrals, not in decoration — that is what makes a single saturated accent
 * read as expensive rather than loud.
 *
 * Two brand tokens, and they are NOT interchangeable:
 *   --brand      a FILL. Button grounds, rules, large figures. White-on-brand
 *                is 3.31:1, which only clears AA for large/bold text.
 *   --brand-ink  TEXT. Links, labels, small figures. 5.18:1 on white.
