/* ── Maximgold Games · shared game landing-page skeleton (v2) ────────────
 *
 * v2 "device frame": the fold is a single rounded mobile frame — the same
 * radius/glow language as the in-game #phaser-parent — holding the game's
 * key visual (dimmed, full-bleed), a centered title lockup, the pill
 * button stack, and the scroll cue. Below the fold: borderless tone cards.
 *
 * Structure contract (per page):
 *   header.topnav > a.brand + span.sig
 *   section.hero > .hero-stage            ← the device frame
 *     ├ .stage-corner.tl / .stage-corner.tr
 *     ├ .stage-visual[aria-hidden]        ← game key visual (page-owned)
 *     └ .stage-content > .title-block(.hero-eyebrow,h1.title,.divider,
 *         p.tagline) + nav.actions(3 .button) + a.scroll-cue
 *   section.info-panel > .info-inner > .intro.glass + .info-section.glass ×3
 *     + .bottom-cta
 *   footer.pagefoot
 *
 * Per-game identity = CSS custom properties (see list) + everything inside
 * .stage-visual + the page .backdrop atmosphere. Radius tokens are a family
 * contract: do not vary per game.
