 # IT Overview
 
-## Website
+## Infrastructure
 
-Hosted on `pncfishandmore.com`. Static/PHP stack via the Netgrimoire `web.yaml` Apache/PHP service.
+| Resource | Details |
+|----------|---------|
+| Domain | `pncfishandmore.com` — managed via ISPConfig |
+| Web server | Apache on NetGrimoire (self-hosted Docker, `web.yaml`) |
+| Email | MailCow + MXRoute relay |
+| DNS | ISPConfig + internal Technitium |
+| Accounting | Bigcapital (Docker on docker5, `accounts.netgrimoire.com`) |
 
-## Email
+---
 
-Handled via MailCow + MXRoute. Domain configured as part of the 8-domain mail setup.
-See [MailCow Domain Setup](/Keystone-Grimoire/Mail/Domain-Setup).
+## Digital Signage System
 
-## POS 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.
 
-*Document POS system here.*
+### TV Pages on Apache
 
-## Network
+| 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 |
 
-*Document store network here — router, AP, any on-site devices.*
+### 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.
