24-24: LGTM! Consider using a consistent border-radius value.

The addition of the rounded class successfully implements the border-radius feature for tags, aligning with the PR objectives. This change enhances the visual presentation without affecting the component's functionality.

For better consistency across the application, consider using a specific border-radius value (e.g., rounded-md or rounded-lg) instead of the generic rounded class. This ensures that all tags have the same degree of roundness throughout the application.

164-164: LGTM: Appropriate image styling

The addition of the rounded-t class to the challenge Image component enhances the visual appeal by rounding the top corners, which is consistent with common design patterns and the PR's objective.

For improved clarity, consider adding a comment explaining why only the top corners are rounded:

className="w-full rounded-t" // Rounds only top corners to match container styling

194-194: LGTM: Consistent tag styling

The addition of the rounded class to the popular topics Link components enhances the visual consistency of the UI and aligns with the PR's objective of adding border radius to tags.

Consider adding an aria-label to improve accessibility for screen readers:

aria-label={`View articles tagged with ${getCamelCaseFromLower(title)}`}

This would provide more context to users navigating with assistive technologies.

Line range hint 161-194: Overall: Consistent UI improvements with potential for refactoring

The changes in this file consistently apply rounded corners to various UI elements, improving the visual appeal and meeting the PR's objective. These modifications are purely aesthetic and don't introduce any functional changes or apparent issues.

Consider refactoring the rounded corner classes into a shared constant or utility function if they are used extensively throughout the application. This could improve maintainability and ensure consistency across the codebase. For example:

// In a utils file
export const ROUNDED_CLASSES = {
  full: 'rounded',
  top: 'rounded-t',
  // ... other variations as needed
};

// In your component
import { ROUNDED_CLASSES } from '@/utils/styleUtils';

// Usage
className={`... ${ROUNDED_CLASSES.full}`}

This approach would centralize these styling decisions and make future updates easier to manage.

1-6: Consider replacing mock data with actual API calls.

The component is currently using mock data (mockContentList, mockVideoSrc) imported from a local mock file. While this is acceptable for development or testing purposes, it's important to replace these with actual API calls or data fetching logic before deploying to production.

Would you like assistance in implementing actual data fetching for this component?

8-13: Approve feature flag check with a minor suggestion.

The feature flag check is well-implemented, providing controlled access to the new feature. However, consider adding a type annotation to the flagEnabled variable for improved type safety:

const flagEnabled: boolean = isFlagEnabled(FEATURE_FLAGS.COURSE_VIDEO);

This change will make the code more robust and self-documenting.

---

15-27: Approve overall structure with a suggestion for video URL.

The component structure and layout are well-organized using Tailwind CSS classes. However, the YouTube video URL is hardcoded, which might not be flexible for different course videos.

Consider passing the video URL as a prop or fetching it from your course data:

interface ContentProps {
  session: Session | null;
  videoUrl: string;
}

const Content = ({ session, videoUrl }: ContentProps) => {
  // ...

  <iframe
    className="aspect-video w-full"
    src={videoUrl}
    title="Course video"
  ></iframe>

  // ...
};

This change will make the component more reusable and easier to update with different video content.

30-60: Approve sidebar content rendering with accessibility suggestion.

The sidebar content rendering is well-implemented with proper conditional rendering and key usage. To improve accessibility, consider adding an aria-label to the list and using more semantic HTML:

- <ul className="divide-y divide-gray-700">
+ <ul className="divide-y divide-gray-700" aria-label="Course content">
  {mockContentList && mockContentList.length > 0 ? (
    mockContentList.map((item, index) => (
-     <li key={index} className="flex flex-row items-center justify-between px-2 py-2">
+     <li key={index} className="flex flex-row items-center justify-between px-2 py-2">
+       <div className="flex flex-row items-center">
+         <SquarePlay className="mr-4 h-5 w-5 text-white group-hover:text-white" aria-hidden="true" />
+         <span>{item.title}</span>
+       </div>
        <CircleCheck
          className={item.watched ? "mr-2 h-5 w-5 text-pink-600" : "mr-2 h-5 w-5 text-white"}
-         aria-hidden="true"
+         aria-label={item.watched ? "Watched" : "Not watched"}
        />
      </li>
    ))
  ) : (
-   <li className="text-center text-gray-500">No content available</li>
+   <li className="text-center text-gray-500" aria-live="polite">No content available</li>
  )}
</ul>

These changes will improve the screen reader experience and overall accessibility of the component.
