Recommendations

• Increase HSTS max-age to at least 1 year and add includeSubDomains
• Improve CSP by adding more specific directives and removing 'unsafe-inline'
• Add X-Frame-Options: DENY or SAMEORIGIN to prevent clickjacking
• Add Referrer-Policy header (recommended: strict-origin-when-cross-origin)
• Consider adding Permissions-Policy to control browser features
