Calendar setup
Add 51–100 staff members, one per line. A random, no-repeat order is generated and saved on this device. The public calendar uses the generic prize message.
Turn on preview mode to test locked doors and daily winners without waiting until December. In normal mode, future doors remain locked according to UK time.
Generic daily prize:
🎁 Congratulations! You've won today's Christmas treat!
Prototype limitation: Data is stored only in this browser. Different devices will NOT share the same winners. This is not ready for staff-wide use until connected to a secure shared database and scheduled server-side draw.
✨ Doors open on their December date, using Europe/London time. This is an interactive local prototype, not a published or secure multi-user service.
