/**
 * cars.zone — Master Design System
 * File: cz-design.css
 * Version: 1.0.0
 * Created: 2026-05-06
 *
 * Architecture:
 *   - CSS variables for all colors, fonts, spacing
 *   - Component classes that work standalone or compose
 *   - Mobile-first responsive (breakpoints at 600px, 900px, 1200px)
 *   - Dark mode ready (variable swap, no rebuild)
 *   - Print stylesheet included
 *   - Accessibility: WCAG AA contrast, focus states, semantic HTML
 *
 * Component classes (all prefixed .cz- to avoid theme conflicts):
 *   .cz-article          — root container for any article body
 *   .cz-hero-strip       — top-of-article severity/ranking strip
 *   .cz-stat-card        — single statistic with label
 *   .cz-stat-grid        — responsive grid of stat cards
 *   .cz-callout          — boxed callout (answer / tip / warning variants)
 *   .cz-data-table       — comparison/severity tables
 *   .cz-big-stat         — single hero number with context
 *   .cz-breakeven-box    — special highlighted block for key insights
 *   .cz-who-grid         — two-column "buy this if / buy that if" cards
 *   .cz-faq-item         — FAQ question/answer block
 *   .cz-divider          — section separator
 *   .cz-editorial-card   — author/methodology card (footer)
 *   .cz-sources          — sources verified footer
 *
 * Built on top of established .art20-* identity from posts published Feb 2026.
 * New articles use .cz-* classes. Existing 13 posts continue using .art20-*
 * (which we will migrate later as low-priority maintenance).
