/**
 * Variant CSS: pricing--quad-grid-blocks
 * Layer 2 — Path B pricing role (brief-bound, Element Count 4, 2026-06-10).
 *
 * A 2×2 mosaic of solid filled tiles, dedicated to exactly four priced
 * services. The four cells butt together inside one outer frame and share thin
 * hairline rules so they read as a single price panel. Each cell carries a
 * small corner index, the service name, a large price (the hero), and a
 * one-line tagline. NO feature lists. Mobile collapses the mosaic to a single
 * stacked column. Scoped to the variant class.
