/**
 * Variant CSS: testimonials--quad-avatar-header-cards
 * Layer 2 — Path B testimonials role (2026-06-10).
 * Exactly FOUR review cards in a 2×2 grid. Each card opens with a TINTED
 * header strip (a light accent wash over the card bg) holding the round avatar
 * + author name + role — the speaker "introduces themselves" first, like a
 * business card — then the quote (with stars) sits in the plain body beneath.
 * Distinct from quad-quote-grid / quad-rating-forward (quote glyph or score is
 * the header; author lives at the foot) and stacked-rows-avatars (avatar at the
 * side of a single full-width row). Scales 2×2 → 1 column on mobile.
 * Header text stays polarity-aware (--text-primary/secondary) so it reads on
 * the light tint in every theme (KI-020 safe — no bg token used as foreground).
 * Every selector scoped to .universal-testimonials--quad-avatar-header-cards.
