/* COH-1489 · cohort.games landing — ONE route, rev. 5
 *
 * Ratified: the paper arm is the site. Frames 4a / 4b (desktop / phone) plus the
 * turn-5 scroll study. The previous two arms are RETIRED:
 *
 *   - the full-bleed scrim arm that was /         → retired
 *   - the framed-card arm that was /framed        → retired (never shipped past rev. 3)
 *
 * There is no [data-arm] switch any more. One page, one stylesheet.
 *
 * Role names only. No tenant names, no raw literals in component rules.
 * Self-hosted assets only; no external fonts or scripts (strict CSP).
 *
 * ── WHAT IS ALREADY ON THE BRANCH ───────────────────────────────────────────
 * The "borrowed" block below duplicates tokens owned by
 * frontend/src/styles/tokens.css. If this page ever runs inside the app's
 * stylesheet scope, DELETE that block — do not reconcile the values. It exists
 * only because marketing/ is served standalone.
 *
 * ── THE PAGE CARRIES TWO INK SETS, ON PURPOSE ───────────────────────────────
 * Paper at the top (bar on the notebook grid, no scrim), scrim at the bottom
 * (footer chrome floating on the footer's render). Each matches its own ground.
 * This is the strongest argument for surface being a real prop on TopBar rather
 * than two hand-maintained sets — see marketing-stack-decision.md.
