/*
 * Revamp ("Aurora glass") flourishes.
 *
 * These rules only apply to the default/revamp theme. They are scoped to
 * :root:not([data-theme="classic"]) so they cover both the explicit
 * data-theme="revamp" attribute AND the no-JS default (no attribute), while
 * never touching the classic theme. Token colours live in 00-base.css; this
 * file adds the things a flat token swap can't: the animated aurora backdrop,
 * frosted glass, gradient accents, glow and motion.
