… in HTTP headers **Severity:** CRITICAL **Vulnerability:** The application was missing clickjacking protection because `frame-ancestors` inside a `<meta>` tag is ignored by browsers according to the W3C specification, providing zero protection. **Impact:** Attackers could embed the application in a hidden iframe on a malicious domain to trick users into performing unintended actions. **Fix:** Removed the non-functional `frame-ancestors` from `src/layouts/Base.astro` and documented that clickjacking protection (`X-Frame-Options: DENY` and `frame-ancestors 'none'`) must be enforced via `public/_headers` (Cloudflare Pages), which is already correctly configured in this repository. **Verification:** Run `pnpm run check` and `bun test` to ensure no regressions. Verified that `public/_headers` correctly contains the security directives.
