 * Dark theme on top of theme-dark.css (`.user-body--dark`), with the public
 * header and footer from site.css. The stage is a slow aurora of brand gold,
 * blue and violet light over a faint grid; the form sits on a frosted glass
 * card whose edge carries a slowly turning gradient. A brand panel beside the
 * card (above it on phones) says what the page is for.
 *
 * Motion: aurora drift, the turning card edge, a staggered rise of the page
 * on load, a shimmer across the main button and focus glows. Only transform
 * and opacity are animated, and everything stops under
 * prefers-reduced-motion. Sizes are fluid (clamp) from phones to large
 * monitors.
