/* TurnUp static site.
 *
 * The palette and the light/dark mechanism are lifted from the app so the two
 * halves of turnup.fyi match: this bucket serves /, the app serves /terms and
 * /privacy, and a visitor crossing between them should not see the brand
 * change. Sources:
 *   nextjs/turnup/www/src/lib/brand/palette.ts  (the ramps)
 *   nextjs/turnup/www/src/app/globals.css       (dark default + light remap)
 *
 * Ramps are copied rather than imported because there is no build step here —
 * that is the point of a static site. If the brand palette moves, move these.
