Below is a single HTML file ready for deployment. It includes a mobile-optimized, high-quality design, YouTube video, photo slideshows, a registration count (50 participants), a timer (as of 2025-11-03 17:00), localStorage-based registration storage and duplicate prevention, and even registration deadline processing. If necessary, you can easily replace it with an actual server-side storage API, as described in the comments. Note: - Data storage: The default is localStorage (safely stored in the browser). When connecting to a server, simply replace the saveRegistration and getRegistrationCount functions. - Timezone: Set to 2025-11-03 17:00 KST (+09:00). - Registration limit: When 50 participants are reached, the button will automatically be marked as "closed." Copy and save as .html to view in a mobile browser. ```html
