-        - `Content-Security-Policy` (CSP) with a restrictive default policy
-          (`default-src 'self'` as a baseline, tightened per-resource as
-          needed). Never use `unsafe-inline` or `unsafe-eval` unless
-          unavoidable, and document the reason.
-        - `X-Frame-Options: DENY` (or `SAMEORIGIN` if framing is required).
-          Prefer the `frame-ancestors` CSP directive as the primary control.
-        - `X-Content-Type-Options: nosniff`.
-        - `Referrer-Policy: strict-origin-when-cross-origin` (or stricter).
-        - `Permissions-Policy` restricting access to browser features the
-          application does not use (camera, microphone, geolocation, etc.).
-    - **Request and response limits:**
-        - Maximum request body size enforced on all endpoints (e.g. Go
-          `http.MaxBytesReader`). Choose a sane default per-route; never accept
-          unbounded input.
-        - Maximum response body size where applicable (e.g. paginated APIs).
-        - `ReadTimeout` and `ReadHeaderTimeout` on the `http.Server` to defend
-          against slowloris attacks.
-        - `WriteTimeout` on the `http.Server`.
-        - `IdleTimeout` on the `http.Server`.
-        - Per-handler execution time limits via `context.WithTimeout` or
-          chi/stdlib `middleware.Timeout`.
-    - **Authentication and session security:**
-        - Rate limiting on password-based authentication endpoints. API keys are
-          high-entropy and not susceptible to brute force, so they are exempt.
-        - CSRF tokens on all state-mutating HTML forms. API endpoints
-          authenticated via `Authorization` header (Bearer token, API key) are
-          exempt because the browser does not attach these automatically.
-        - Passwords stored using bcrypt, scrypt, or argon2 — never plain-text,
-          MD5, or SHA.
-        - Session cookies set with `HttpOnly`, `Secure`, and `SameSite=Lax` (or
-          `Strict`) attributes.
-    - **Reverse proxy awareness:**
-        - True client IP detection when behind a reverse proxy
-          (`X-Forwarded-For`, `X-Real-IP`). The application must accept
-          forwarded headers only from a configured set of trusted proxy
-          addresses — never trust `X-Forwarded-For` unconditionally.
-    - **CORS:**
-        - Authenticated endpoints must restrict `Access-Control-Allow-Origin` to
-          an explicit allowlist of known origins. Wildcard (`*`) is acceptable
-          only for public, unauthenticated read-only APIs.
-    - **Error handling:**
-        - Internal errors must never leak stack traces, SQL queries, file paths,
-          or other implementation details to the client. Return generic error
-          messages in production; detailed errors only when `DEBUG` is enabled.
-    - **TLS:**
-        - Services never terminate TLS directly. They are always deployed behind
-          a TLS-terminating reverse proxy. The service itself listens on plain
-          HTTP. However, HSTS headers and `Secure` cookie flags must still be
-          set by the application so that the browser enforces HTTPS end-to-end.
-
-    This list is non-exhaustive. Apply defense-in-depth: if a standard security
-    hardening measure exists for HTTP services and is not listed here, it is
-    still expected. When in doubt, harden.
