/**
 * Security headers applied to every response. Per audit-pass-#3 finding:
 * the previous config emitted no CSP, X-Frame-Options, HSTS, or
 * X-Content-Type-Options — the app was open to clickjacking + MIME
 * sniffing.
 *
 * CSP notes:
 *   - 'unsafe-inline' on style-src is required by Tailwind's runtime
 *     style injection and Radix; revisit when Tailwind v4 ships a
 *     nonce story.
 *   - 'unsafe-eval' on script-src is dev-only — Next dev uses eval for
 *     HMR. Production drops it.
 *   - connect-src allows ws/wss for Socket.IO and https: for outgoing
 *     fetches; tighten in prod via per-port branding URLs once we move
 *     the s3 image references into a known allowlist.
 *   - img-src https: is wide because port branding pulls from
 *     s3.portnimara.com plus per-port image URLs configured at runtime.
