## Digital Signage System

Three FireTV devices display live price board slides on in-store TVs. Each TV runs ScreenLite kiosk app loading an Apache HTML page, which fetches a Google Slides PNG export and refreshes it every 5 minutes via JavaScript.

### TV Pages on Apache

| File | Slide Deck | Purpose |
|------|-----------|---------|
| `left.html` | Saltwater fish | Main fish price board |
| `right.html` | Secondary | Freshwater or secondary display |
| `inverts.html` | Invertebrates | Inverts price board |

### Google Slides Deck IDs

| Deck | Slide ID |
|------|---------|
| Left (saltwater fish) | `1S3j0K1QlWAtkjq73E73At3gz9vWp9vVr_yZswUHiyN8` |
| Right (secondary) | `1mWzgisxMQAFAhME9HXY_PEK0v_hIuQ4Md0PQS10ES8Q` |
| Inverts | `1nzunM4pQxqmW82_Ab0rrOsV4QuO8G5TVUDodplI_4tY` |

PNG export URL format: `https://docs.google.com/presentation/d/<ID>/export/png?sz=s1920`

Use `sz=s1920` for sharper text. If display looks soft, increase canvas size in Google Slides settings.

### Critical: ScreenLite Does Not Respond to Meta-Refresh

ScreenLite ignores `<meta http-equiv="refresh">`. All TV page refreshes use JavaScript `setInterval` image src swap only:

```javascript
setInterval(function() {
  var img = document.getElementById('slide');
  img.src = SLIDE_URL + '?t=' + Date.now();
}, 300000); // 300,000ms = 5 minutes
```

### Force Immediate Refresh

Force-stop ScreenLite on the FireTV and relaunch. It reloads the Apache URL and picks up the latest PNG immediately.
