/**
 * Variant CSS: pricing--tiers-quartet-row
 * Layer 2 — Path B pricing role (brief-bound, Element Count 4, 2026-06-10).
 *
 * Four equal tier cards on a single row (a fixed 4-up quartet, dedicated to
 * exactly four priced services). Each card carries a sequential index pill at
 * the top, the service name, an oversized price as the visual hero sitting over
 * a short accent underline rule, then a one-line tagline. NO feature lists —
 * price + name + optional tagline only. At 4-up the cards pin to a quarter
 * width each; tablet drops to a 2×2, mobile to a single stack. Scoped to the
 * variant class.
