Astro defaults to static output; server output makes pages render on demand unless route-level prerendering changes that. First decide whether the hot route truly needs SSR.
Inspect astro.config, adapter options, output, route-level prerender, dynamic params, middleware, and whether the content is shared across visitors. Compare route cache result and request volume.
Do not prerender or cache personalized, preview, cart, checkout, or auth-gated pages. Do not change output mode for the whole app when one route-level flag is enough.
Name the Astro output mode, route-level prerender state, observed route signal, and exact config or page line.
