/**
 * Variant CSS: offer--quad-icon-tile-grid
 * Layer 2 — Path B universal offer variant (authored 2026-06-10).
 *
 * Concept: EXACTLY FOUR services as a tight, symmetric 2×2 grid of ICON-LED
 * tiles. Each tile is dominated by a large round icon medallion at the top,
 * then a short service name (h3), a one-line description and the price pinned
 * to the bottom edge. The prominent accent-tinted medallions carry the visual
 * hierarchy — that is the signature of this variant.
 *
 * Differentiator vs sibling offer count-4 variants:
 *   - quad-card-grid: large outlined ordinal + text-forward cells.
 *   - quad-price-forward-cards: price is the dominant element.
 *   - four-compact-columns: single tight row, no tiles.
 *   THIS one: 2×2 matrix where a big icon medallion leads every tile.
 *
 * Tokens: semantic only (Layer 2 API). Medallion uses an accent tint
 * (color-mix with --accent ~12%) behind an --accent-stroked glyph, so it reads
 * as a friendly, legible signal on both light and dark themes without ever
 * using a bg-token as a foreground (KI-020).
