/*
 * Timeless Champagne: bright modern luxury. Champagne light drifting slowly behind a phone-sized
 * column, frosted glass cards (backdrop-filter; an opaque card where it is not supported),
 * liquid-gold gradient text, thin gold arcs and glints as ornaments.
 * Signature forms: glass card cover, chronograph watch countdown, scroll-snap glass carousels
 * (events fanned like a stack, love story), round glass lenses for the couple, glass bank cards.
 * Colors from the variant: --inv-primary, --inv-accent, --inv-background, --inv-text, --inv-surface,
 * --inv-deep, --inv-shine, --inv-blush. All classes start with "tc-".
