You are absolutely right! My apologies for the oversight. The previous app/[subject-slug]/page.tsx file was a Next.js App Router convention, but your project is a React application using react-router-dom. This means the dynamic routing was not correctly set up for the "General Notes" page.

To fix this, we need to:

1. Create a new React component file, let's call it SubjectNotesPage.jsx, in your frontend/src/pages/ directory. This file will contain the logic to map the URL slug to the subject name.
2. Update your frontend/src/App.js to include a route that uses this new SubjectNotesPage.

Here are the corrected files:

To fix the issue:

1. Create a new file named SubjectNotesPage.jsx inside frontend/src/pages/ and paste the content from the first code block.
2. Replace the content of your existing frontend/src/App.js with the second code block.
3. Delete the file app/[subject-slug]/page.tsx as it's not used in your React project.
4. Restart your frontend development server (npm start in your frontend directory).

Now, when you click on "General Notes" (or any other subject card), it should correctly display the subject name on the second page.

You are absolutely right to point that out! My apologies for the persistent issue. It seems there was a subtle redundancy in the header text for "General Notes" and a potential for the "Unknown Subject" fallback if the slug mapping wasn't perfectly aligned.

I will provide updated code for HomePage.jsx, SubjectNotesPage.jsx, NotesGeneratorContent.jsx, and NotesInputForm.jsx to ensure the subject name is displayed correctly and gracefully for "General Notes" and all other subjects.

Here are the corrected files. Please replace your existing files with these:

To apply these changes:

1. Replace the content of frontend/src/pages/HomePage.jsx with the first code block.
2. Replace the content of frontend/src/pages/SubjectNotesPage.jsx with the second code block.
3. Replace the content of frontend/src/components/NotesGeneratorContent.jsx with the third code block.
4. Replace the content of frontend/src/components/NotesInputForm.jsx with the fourth code block.
5. Ensure you have deleted the app/[subject-slug]/page.tsx file if it still exists, as it's a Next.js file not used in your React project.
6. Restart your frontend development server (npm start in your frontend directory).

This comprehensive update should ensure that "General Notes" is correctly displayed on the second page, and the text is appropriate for a general topic generator.
