## Security

### Security Headers (D — 40/100)

*3 of 10 headers properly configured*

- **[WARNING]** HSTS is missing includeSubDomains — Without includeSubDomains, subdomains can still be accessed over HTTP.
- **[WARNING]** X-Content-Type-Options header is missing — This header prevents MIME-type sniffing, which can lead to XSS attacks. Set it to 'nosniff'.
- **[WARNING]** X-Frame-Options header is missing — This header prevents clickjacking by controlling who can embed your page in a frame. Set it to DENY or SAMEORIGIN.
- **[WARNING]** Referrer-Policy header is missing — Controls how much referrer information is sent with requests. Set to 'strict-origin-when-cross-origin' or stricter.
- **[WARNING]** Permissions-Policy header is missing — Controls which browser features (camera, microphone, geolocation) are allowed. Set it to restrict unused features.
- **[PASS]** Content-Security-Policy is present
- **[WARNING]** Cross-Origin-Opener-Policy header is missing — COOP isolates your browsing context, preventing cross-origin side-channel attacks. Set to 'same-origin'.
- **[WARNING]** Cross-Origin-Embedder-Policy header is missing — COEP prevents loading cross-origin resources without explicit permission. Required for SharedArrayBuffer and high-resolution timers.
- **[PASS]** X-Powered-By header is not present

### Transfer Efficiency (B — 80/100)

*89% efficient*

- **[INFO]** Transfer efficiency: 89% — An estimated 920 KB (11%) could be eliminated: 0 KB via better compression, 0 KB via modern image formats, 920 KB of unused JavaScript. This wasted data produces 0.21g of unnecessary CO2 per page view.
