/* HYPERNIX — SITE
 *
 * The public website, written in the launcher's vocabulary rather than in a
 * fourth one of its own. Before this the landing page carried its own
 * typography (system sans), its own accent (one flat yellow), its own idea of a
 * button, and a footer whose brand mark was the letter H in a box — so a player
 * who downloaded the launcher and then opened the site was looking at two
 * products with the same name.
 *
 * Everything here is taken from HQLauncher/renderer/css: the Unbounded family,
 * the near-black field, the ink, the section colours, the 12/18/999 radius
 * scale, depth via --lift instead of hairline borders, and the two springs. The
 * token NAMES are deliberately the launcher's own, so a rule can be moved
 * between the two codebases without translation.
 *
 * Three things this sheet owns that the launcher does not need:
 *   1. A scroll layer. Sections arrive rather than being simply present —
 *      [data-reveal] is off-screen until site.js says otherwise, and the whole
 *      thing degrades to "visible" when JavaScript never runs.
 *   2. A depth layer. The hero, the feature slabs and the product cards are
 *      real 3D — perspective, transform-style: preserve-3d, translateZ — not a
 *      drop shadow pretending to be one.
 *   3. A width. The launcher is a fixed window; this has to survive 360px.
