/*
 * ============================================
 *  CARD COMPONENTS — REUSABLE ACROSS ALL PAGES
 * ============================================
 *
 * Cards are the most-used component on the site. They appear in:
 * - Services (service cards)
 * - Portfolio (project cards)
 * - Shop (product cards)
 * - Blog (post cards)
 *
 * We define a base .card class with shared styles, then use
 * modifier classes (.card--service, .card--blog, etc.) for
 * section-specific differences. This is the DRY principle:
 * Don't Repeat Yourself.
