A beautiful event management web app for Sundays in SF sessions, featuring live San Francisco sky gradient backgrounds and a whimsical Apple HIG-inspired design.

• Pre-Session Screen: Welcome message with WiFi QR code and session schedule
• Timer Screen: Create and run timers with animated sunrise-to-sundown gradient backgrounds
• Closeout Screen: Thank you message with QR codes for next session and Commons Public Hours
• Live Sky Gradients: Real-time San Francisco sky rendering using atmospheric scattering simulation

Configure these in your Val Town environment:

SUNDAYS_WIFI_SSID=your-wifi-network-name
SUNDAYS_WIFI_PASSWORD=your-wifi-password
SUNDAYS_NEXT_SESSION_URL=https://your-rsvp-link
SUNDAYS_COMMONS_URL=https://your-commons-link

Replace the placeholder in shared/types.ts:

export const ALARM_SOUNDS: AlarmSound[] = [
  {
    id: "mr-blue-sky",
    name: "Mr. Blue Sky",
    url: "YOUR_AUDIO_FILE_URL", // Replace PLACEHOLDER_URL with your hosted audio
  },
];
