            Recommendations
          
          - • Add Strict-Transport-Security header with max-age of at least 1 year
 - • Add Content-Security-Policy header to prevent XSS attacks
 - • Add X-Frame-Options: DENY or SAMEORIGIN to prevent clickjacking
 - • Add X-Content-Type-Options: nosniff
 - • Add Referrer-Policy header (recommended: strict-origin-when-cross-origin)
 - • Consider adding Permissions-Policy to control browser features
