/* Autorestage — marketing site, part 1: tokens, base, nav, hero, spin, marquee.
 *
 * Two themes from one list of token NAMES. The light values sit on :root; the
 * dark values are written once for the dark scopes and once more inside the
 * system-preference query, because a media query cannot share a rule body.
 * The dark scopes are the page in dark mode AND the sections that stay dark
 * whatever the page does (the hero, the stats band, the final call, the code
 * card, and the nav while it floats over the hero): custom properties
 * inherit, so declaring the dark set on those elements flips everything
 * inside them.
 *
 * This replaced light-dark(), which did the same thing in fewer lines but has
 * no fallback: a browser without it (Safari before 17.5, Chrome before 123)
 * finds every colour token invalid, and the hero headline went black on
 * black. Section styles live in sections.css. */
