The Virtual Lab section has inconsistent navigation and routing: - Virtual Lab home page shows Physics labs, but Physics does not have a dedicated page like Chemistry. - Clicking Physics opens a dropdown instead of a subject page, unlike Chemistry. - Chemistry URL contains duplicated path: /virtual_lab/virtual_lab/chemistry/ - Physics dropdown menu gets hidden behind content when a lab is open. <img width="572" height="55" alt="Image" src="https://github.com/user-attachments/assets/69f33a68-5299-44ba-97e3-dfc91df60d44" /> <img width="1532" height="262" alt="Image" src="https://github.com/user-attachments/assets/e424894e-2d7d-4aed-9c02-d65cae35d691" /> <img width="1919" height="896" alt="Image" src="https://github.com/user-attachments/assets/212a90ba-a023-427f-9080-cfb686f3c3dc" />
