## Security

### Security Headers (F — 30/100)

*3 of 10 headers properly configured*

- **[PASS]** Strict-Transport-Security is properly configured
- **[WARNING]** X-Content-Type-Options header is missing — This header prevents MIME-type sniffing, which can lead to XSS attacks. Set it to 'nosniff'.
