Astro is a modern site builder with web best practices, performance, and DX front-of-mind.

/**
* The error strategy used during static build / prerendering.
*
* - For 500 errors, returns the original response if present, otherwise
*   throws so the build surfaces the underlying error to the developer.
* - For other errors (e.g. 404), delegates to `renderDefaultError` with
*   `prerenderedErrorPageFetch` cleared (the build pipeline can't fetch
*   prerendered pages the way production SSR can).
