   - ❌ Avoid: `<component :is="`icon-${name}`" />`
   - ✅ Use: `<icon-foo v-if="condition" />` with `v-if`/`v-else-if`/`v-else` directives
 - **In TypeScript/TSX files**: Auto-import does NOT work. You must explicitly import icons using the `~icons/` prefix:
+
   ```tsx
   import IconMenuRounded from '~icons/material-symbols/menu-rounded';
 
   // Then use in JSX/TSX
   const menuOption = {

 Project has multiple UI frameworks configured:
 
 - **Naive UI**
+  - **Form Layout**: When using `NGrid` for form layouts, prefer `NFormItemGi` over nesting `NFormItem` inside `NGridItem` for more concise code.

+    ```vue
+    <!-- ❌ Avoid: Verbose nesting -->
+    <NGrid :cols="4">
+      <NGridItem>
