+/**
+ * Component to set the screen title.
+ *
+ * Can be used inside Stack.Screen in a layout or directly inside a screen component.
+ *
+ * @example
+ * String title in a layout:
+ * ```tsx
+ * import { Stack } from 'expo-router';
+ *
+ * export default function Layout() {
+ *   return (
+ *     <Stack>
+ *       <Stack.Screen name="index">
+ *         <Stack.Screen.Title large>Home</Stack.Screen.Title>
+ *       </Stack.Screen>
+ *     </Stack>
+ *   );
+ * }
+ * ```
+ *
+ * @example
+ * String title inside a screen:
+ * ```tsx
+ * import { Stack } from 'expo-router';
+ *
+ * export default function Page() {
+ *   return (
+ *     <>
+ *       <Stack.Screen.Title>My Page</Stack.Screen.Title>
+ *       <ScreenContent />
+ *     </>
+ *   );
+ * }
+ * ```
+ *
+ * @example
+ * Custom component as the title using `asChild`:
+ * ```tsx
+ * import { Stack } from 'expo-router';
+ *
+ * export default function Layout() {
+ *   return (
+ *     <Stack>
+ *       <Stack.Screen name="index">
+ *         <Stack.Screen.Title asChild>
+ *           <MyCustomTitle />
+ *         </Stack.Screen.Title>
+ *       </Stack.Screen>
+ *     </Stack>
+ *   );
+ * }
+ * ```
+ *
+ * > **Note:** If multiple instances of this component are rendered for the same screen,
+ * the last one rendered in the component tree takes precedence.
