/**
 * clock.css
 *
 * Clock cards, event/local time columns, timezone display, UTC badges, time difference marker, countdown, and current-time links. Includes route-specific and mobile sizing overrides.
 *
 * Sections:
 * 1. Shared clock typography/card placement
 * 2. Countdown and event/local time columns
 * 3. Time-difference marker and timezone badges
 * 4. Manual timezone/current-time controls
 * 5. Responsive clock layouts
 *
 * Troubleshooting:
 * - `.has-event` changes the card from one clock to event/local columns.
 * - Mobile widths are intentionally tight; test long city/timezone labels.
