Security Headers Priority Fixes

Instead of changing all headers at once, phased hardening by risk-impact is usually safer.

Prioritization

  1. First wave: X-Content-Type-Options, X-Frame-Options
  2. Second wave: Referrer-Policy, Permissions-Policy
  3. Third wave: CSP and HSTS with stage validation

For analysis, use Security Headers Analyzer.
