/**
 * ═══════════════════════════════════════════════════════════════════════════════════
 * BALAM AI - Card Components (Global)
 * ═══════════════════════════════════════════════════════════════════════════════════
 *
 * Stat cards + chart cards, promoted from pages/dashboard.css to a GLOBAL,
 * fully token-driven component so they render correctly everywhere — including
 * the staff /styleguide page, which does NOT load pages/dashboard.css.
 *
 * Self-contained: uses ONLY var(--balam-*) design tokens for colors, shadows,
 * radii and borders. No hardcoded hex. Because the cards reference tokens, they
 * automatically pick up the [data-theme="dark"] overrides and render correctly
 * on both light pages and dark surfaces — no theme-specific hacks needed.
 *
 * Neumorphic look: soft raised card shell
 *   background    → var(--balam-card-bg)
 *   border        → 1px solid var(--balam-card-border)
 *   border-radius → var(--balam-card-radius)
 *   box-shadow    → var(--balam-card-shadow) / hover var(--balam-card-shadow-hover)
 *
 * @requires shared-variables.css  (design tokens / --balam-* custom properties)
 * ═══════════════════════════════════════════════════════════════════════════════════
