+        ## MOBILE APP / ADD TO HOME SCREEN
+
+        Powder Coating Logix works in any phone browser but can also be installed as a **home screen app** (Progressive Web App / PWA) for a better experience. Installation is especially important for shop floor workers who use the label scanner or log usage from their phone.
+
+        **Why install it:**
+        - Opens full-screen with no browser address bar — feels like a native app
+        - Camera permission is granted once and remembered permanently (instead of being asked every browser session)
+        - Faster to launch — one tap from the home screen
+
+        **iOS (iPhone / iPad) — must use Safari:**
+        iOS only supports home screen installation from Safari. Installing from Chrome or Firefox on iOS creates a regular browser bookmark that does NOT give the standalone or camera-permission benefits.
+        1. Open the app in **Safari** (not Chrome or Firefox)
+        2. Tap the **Share button** (box with arrow pointing up) at the bottom of Safari
+        3. Scroll down and tap **Add to Home Screen**
+        4. Confirm the name and tap **Add**
+        The app icon now appears on the home screen and launches in full-screen mode.
+
+        **Android — Chrome:**
+        1. Open the app in Chrome
+        2. Chrome may show an **Install App** banner automatically — tap it
+        3. If no banner: tap the **menu (⋮)** in the top-right → **Add to Home Screen** or **Install App**
+
+        **Dashboard install banner:** When a mobile user who has not yet installed the app opens the Dashboard, a banner at the top of the page shows device-specific installation instructions. The banner disappears automatically once the app is running as a standalone home screen app, and can also be dismissed manually — it will not reappear after dismissal.
