+# Error Page
+
+A simple error page template for browser loading failures. Unlike other special pages, this page does not use messaging—native interacts via string interpolation and a global callback.
+
+## String Interpolation
+
+Native performs string replacement on the HTML before loading:
+
+| Variable | Description |
+|----------|-------------|
+| `$HEADER$` | Error title text |
+| `$ERROR_DESCRIPTION$` | Error description text |
+| `$THEME_VARIANT$` | Theme variant name (falls back to default if not replaced) |
+
+## Runtime Theme Updates
+
+Native can update the theme by calling:
+
+```javascript
+window.onChangeTheme({ themeVariant: 'coolGray' });
+```
+
+**Payload:**
+```json
+{
+  "themeVariant": "violet"
+}
+```
+
+Available theme variants: `default`, `coolGray`, `slateBlue`, `green`, `violet`, `rose`, `orange`, `desert`
