/**
 * Variant CSS: testimonials--quad-alternating-accent-cards
 * Layer 2 — Path B testimonials role (2026-06-11).
 * Exactly FOUR review cards in a balanced 2×2 grid laid out as an accent/neutral
 * CHECKERBOARD: two diagonally-opposite cards (1 & 4) are FILLED with the accent
 * colour, the other two (2 & 3) stay neutral with a hairline border — a rhythmic
 * alternating pattern is the signature. Each card: stars, quote (flex-grows so the
 * feet align), divider-separated author footer.
 * Distinct from quad-quote-grid (uniform quote-mark cards), quad-rating-forward,
 * quad-zebra-aligned-rows, quad-avatar-header-cards, quad-pullmark-grid and
 * four-up-compact-row: only this one alternates filled vs bordered diagonally.
 * Scales 2×2 → 1 column on mobile.
 * CRITICAL: filled cards (.universal-testimonials__card--accent) put ALL text and
 * the stars on var(--on-accent,#fff) — never --on-dark (white is invisible on the
 * light-accent themes: charcoal-mono-luxe / butter / peach). KI-020: no bg token
 * is ever used as a text colour.
 * Every selector scoped to .universal-testimonials--quad-alternating-accent-cards.
