/* Pricing Page — Tier-Based Design System
 *
 * 3-tier architecture:
 *   Tier 1: Hero snapshot (above the fold, answers "how much?" in 3 seconds)
 *   Tier 2: Service categories with sticky tabs + pricing cards
 *   Tier 3: Trust & policies (expandable, bottom)
 *
 * Uses design tokens from design-tokens.css.
 * Mobile-first with progressive enhancement.
