Important

Error:

• PDFs sometimes fail to load inside the mobile viewer with a Network / CORS error.

Cause:

• Some book links were served over HTTP instead of HTTPS,
• or the server did not include proper CORS headers (Access-Control-Allow-Origin).

Solution:

• Enforced HTTPS links for all book resources.
• Updated the Express server to include:
  • Access-Control-Allow-Origin: *
  • Access-Control-Allow-Methods: GET
• Added validation to reject insecure PDF URLs in the database.
