- Add /health proxy block with rate limiting for external uptime monitoring - Fix Permissions-Policy on API responses: add passkey directives - Strengthen CSP: add frame-ancestors 'none' + upgrade-insecure-requests - Relax backend healthcheck interval from 10s to 30s (reduce overhead) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
