// QA-only Netlify Function used to test Prerender's handling of 4xx

// anything else/unset -> HTTP 200, minimal HTML body
// Reached publicly via /qa-block (see redirect in netlify.toml).

// Kept as its own function (not folded into qa-code.ts) because the
// build-time env toggle does not fit the generic fixed-status
// dispatcher — same reasoning as qa-status.ts.
