 ## Angular Best Practices
 
 - Always use standalone components over NgModules
-- Must NOT set `standalone: true` inside Angular decorators. It's the default.
+- Must NOT set `standalone: true` inside Angular decorators. It's the default in Angular v20+.
 - Use signals for state management
 - Implement lazy loading for feature routes
 - Do NOT use the `@HostBinding` and `@HostListener` decorators. Put host bindings inside the `host` object of the `@Component` or `@Directive` decorator instead
 - Use `NgOptimizedImage` for all static images.
   - `NgOptimizedImage` does not work for inline base64 images.
