/* ─── tests.zadeteto.com PORTAL — premium / glass redesign ───────────────────
 * Extends landing-zd.css (ZaDeteto purple tokens). Apple-ish: frosted glass

 * refract, and a multi-vector scroll-reveal (up / left / right / rotate / scale).
 * Brand stays purple + white. Motion honours prefers-reduced-motion. */
