 * IndianMarriage - im-components.css
 * Component library: 8 .im-* primitives consuming CC-02a tokens.
 *
 * Wave-2 (CC-02b-wave2): the in-file `:root` stub from Wave-1 is removed.
 * Tokens are now sourced directly from /static/css/tokens.css via the @import
 * below. Primitives consume canonical token names (`--marriage-gold`,
 * `--neutral-slate-700`, `--radius-lg`, `--shadow-2`, etc.) from tokens.css.
