LAHX Countdown (Next.js)

A fullscreen judging-round countdown page intended for attendees (read-only) with a hidden admin settings panel.

Features

• Round countdown: Hours / minutes / seconds until the configured end time.
• Round title + end-time summary: Displays the round name and a human-friendly end-time string.
• Auto-hide settings (attendee-safe):
  • Once Round name is non-empty and Round ends is in the future, the settings UI hides.
  • When the countdown finishes, settings become visible again automatically.
• Hidden admin reveal:
  • While the timer is running, Shift-click the logo to reveal/hide the settings panel.
  • Keyboard: focus the logo, then press Shift+Enter or Shift+Space.
• Persists settings in the browser via localStorage:
  • lah-judging-round-name
  • lah-judging-target-ms

How to use (admin)

1. Open the page in the browser.
2. Enter Round name.
3. Set Round ends (uses your computer’s local timezone/clock).
4. As soon as both are set and the end time is in the future, the settings UI hides for attendees.
5. If you need to adjust mid-round, Shift-click the logo to reveal settings.
