/**
 * Accessible Events Calendar — front-end styles.
 *
 * Design notes:
 * - Every color/spacing value is a CSS custom property with a WCAG 2.2 AA
 *   compliant fallback, so the calendar is safe out of the box and fully
 *   restylable from Settings > Event Calendar or a theme stylesheet.
 * - --aec-font defaults to "inherit" so the calendar always matches the
 *   surrounding theme's font unless explicitly overridden.
 * - All type sizes use rem/em so the layout respects user browser zoom
 *   and OS text-size settings (WCAG 1.4.4 Resize Text).
 * - Interactive targets are at least 44x44px (exceeds the WCAG 2.2 2.5.8
 *   24px minimum). Focus states use a highly visible outline (2.4.7,
 *   2.4.11) and are never removed without a visible replacement.
 * - Respects prefers-reduced-motion.
