/* AETHER — design system for the AI app studio.
 *
 * Codename: Aether. Identity: midnight + electric violet + cyan accent.
 * Replaces the prior gold/Cinzel cinematic theme with something that feels
 * like a living AI lab — glass surfaces, soft neon, type-on motion.
 *
 * One file, scoped via :root tokens + .ae-* classes. Drop-in via
 *     <link rel="stylesheet" href="/static/aether.css">
