+# Browser security boundary
+
+The browser bundle is public. Secrets, token lifecycle, raw HTML injection,
+dynamic code execution, untrusted script URLs, and public production source
+maps are prohibited defaults.
+
+`config/hosting/security-headers.json` is the declared header set. Hosting
+verification compares that declaration with live responses. CSP deliberately
+omits `unsafe-inline` and `unsafe-eval`; production code and built assets must
+remain compatible with that baseline.
+
+Route guards are UX hints and client validation does not replace backend
+authorization or validation.
