/**
 * Variant CSS: offer--quad-card-grid
 * Layer 2 — Path B universal offer variant (authored 2026-06-10).
 *
 * Concept: EXACTLY FOUR services as a balanced 2×2 card matrix. Each cell is a
 * card carrying a large outlined ordinal in the corner + service title (h3) +
 * 2-3 line description + optional price pinned to the bottom edge. Symmetric
 * quadrants, resting elevation, hover lift + accent edge. The calm "four equal
 * pillars" layout — no single service dominates.
 *
 * Differentiator vs sibling offer variants:
 *   - icon-cards-3col / trio-accent-cards: 3-up rows, icon chips.
 *   - featured-plus-trio (count-4 sibling): asymmetric 1 large + 3 small.
 *   - four-compact-columns (count-4 sibling): single tight row, no cards.
 *   THIS one: full 2×2 matrix of equal numbered cards + price.
 *
 * Tokens: semantic only (Layer 2 API). Cards sit on --background-card so they
 * LIFT on dark themes; on light themes the border + resting shadow carry the
 * elevation. Ordinal = --accent outlined glyph (text-stroke fallback to fill).
