## Security

### Security Headers (B — 75/100)

*6 of 10 headers properly configured*

- **[WARNING]** Referrer-Policy header is missing — Controls how much referrer information is sent with requests. Set to 'strict-origin-when-cross-origin' or stricter.
- **[PASS]** Permissions-Policy is set
- **[PASS]** Content-Security-Policy is present
- **[INFO]** Cross-Origin-Opener-Policy is set but not 'same-origin'
