/**
 * Variant CSS: pricing--quad-tier-ramp
 * Layer 2 — Path B pricing role (brief-bound, Element Count 4, 2026-06-10).
 *
 * Four tiers in a row arranged as an ascending ramp left→right, dedicated to
 * exactly four priced services. A subtle step ramp (rising height via a small
 * upward offset, strengthening border + shadow) implies a "good / better /
 * best / max" progression; each card carries a step number, name, large price
 * and a one-line tagline, with the top tier (DOM :last-child) the most
 * emphasised (accent border + filled step badge). Distinct from
 * tiers-quartet-row, which presents four EQUAL cards with no hierarchy. NO
 * feature lists. At 4-up the cards pin to a quarter width; tablet drops to a
 * 2×2 and resets the ramp offsets; mobile stacks to one column. Scoped to the
 * variant class.
 *
 * The step number is driven by a section-level counter in DOM order so it stays
 * correct (1-4) even if the loader renumbers tiers.
