//! Guard — Mizan SSR is hand-rolled (bare renderer + AFI data injection +
//! injected kernel). No frontend adapter imports an SSR runtime / meta-framework
//! (Next, Nuxt, SvelteKit) or a server-functions layer (RSC / Flight).
//!
//! React Server Components and the Flight serialization protocol carry
//! CVE-2025-55182 ("React2Shell" — unauthenticated remote code execution,
//! CVSS 10.0): the server deserializes a client-supplied Flight payload and an
//! attacker reaches prototype-pollution → RCE.
//!
//! Mizan renders **synchronously from props** — data is fetched server-side
//! through the AFI and passed in, never deserialized from a client payload — so
//! it sits structurally outside that attack surface. This test keeps it there:
//! it goes red the instant any RSC / Flight / streaming surface enters the
//! authored SSR source or its dependencies. Absence is not enough; this is the
//! forcing function that makes re-entry loud.

/// Tokens that only appear when RSC / Flight / streaming rendering is in play.
