// `force-dynamic` removed in favor of `experimental.cacheComponents` (Next 16).
// `ConditionalNavigation` reads `cr_session` server-side (and `usePathname()`
// transitively in `ConditionalNavigationClient`) — both are uncached, so it
// lives behind a `<Suspense>` boundary so the rest of the layout stays in the
// static shell while the session/pathname-aware nav streams in. The fallback
// is `null` because any non-null fallback would also need to live in the
// static shell, and the nav's chromeless decision depends on the pathname
// (e.g. `/create/*` and `/login` render no top-nav). Brief blank-nav while
// the dynamic island resolves is acceptable on signed-in product surfaces.
//
// Signed-in product surfaces (`/create/*`, `/login`) run without the marketing
// footer. `/profile` adds it via `profile/layout.tsx`. Per-route chrome (e.g.
// CreateFlow) is composed in nested layouts.
