/* ==============================================================
 * Modern Cards — global design system
 * --------------------------------------------------------------
 * Applies the polished card style (used on /president/reports)
 * to every .card across the system. Loaded after style.css and
 * before accessibility-fixes.css.
 *
 * Goals:
 *   - Soft 16px radius, subtle border, deep on-hover shadow
 *   - Smooth lift on hover (no jank)
 *   - Same look in LTR + RTL + dark mode
 *   - Respect prefers-reduced-motion (W3C WAI 2.3.3)
 *   - Visible focus-ring (W3C WAI 2.4.7)
 *
 * Opt-out per card: add class `.no-modern` to keep legacy look.
