/**
 * Variant CSS: partners--become-partner-tiers
 *
 * Partner recruitment as three comparison cards (Bronze/Silver/Gold), each with a
 * rank name, a short descriptor, a perks checklist and its own "join" CTA. The
 * middle tier is featured on a dark surface with a ribbon badge. Distinct from
 * tiered-partners (sponsor chip rows) and become-partner-cta (single dark panel):
 * here the visitor compares packages and picks an entry level.
 *
 * KI-020: the featured (dark) card uses var(--text-on-dark,#fff) for body text and
 * an accent lift — color-mix(in srgb, var(--accent) 60%, var(--on-dark,#fff)) — so
 * the accent stays readable on dark. Cards stack to one column on mobile.
