 *
 * Amber discipline: --warm / dark-mode --accent is the only saturated colour in
 * the system. If two things are amber in one viewport, one of them is wrong —
 * which is why the page has exactly one filled button, the hero's download CTA.
 *
 * The style guide says the OS picks the scheme and there is no toggle, so both
 * palettes are declared under color-scheme and dark reads prefers-color-scheme.
