 - • Improve CSP by adding more specific directives and removing 'unsafe-inline'
 - • Consider adding Permissions-Policy to control browser features

            Recommendations
          
          - • Consider using critical flag (flags=128) for stricter CAA enforcement
 - • Consider adding 'issuewild' records to control wildcard certificate issuance
