/* PARIUM gated demo — gate + shell chrome (PP-3, #580).
 *
 * The site's light Airbnb-school --p-* system (site/assets/site.css, PP-2 #579): warm
 * off-white ground, warm near-black ink, one amber-clay accent, soft elevated cards,
 * pill CTAs, system-ui humanist stack, zero remote assets. The GAME stays the dark
 * stage moment (handoff §4) — it lives inside the iframe and carries its own canvas.css;
 * this file styles only the studio chrome around it. Mobile-first: 390px composed first,
 * wider viewports centre the same column. Single deliberate LIGHT commit (like the site).
