Elite CSP detected — nonces/hashes + default-src 'none' + locked-down directives

A Content Security Policy (CSP) is a security header that tells browsers exactly which scripts, images, and other resources are allowed to load on your site. An elite CSP uses cryptographic tokens (nonces or hashes) to allow only approved code. This is the gold standard for preventing cross-site scripting (XSS) attacks, where hackers inject malicious code into your pages. Having it means your site blocks most injection attacks automatically. Great work — your CSP is at the highest tier. Continue reviewing it when you add new third-party scripts to ensure none require weakening the policy.
