 * Netlify's proxy copies the request's query string onto any redirect whose
 * Location has none, so a bare 302 out of a sign-in callback lands the browser
 * on a page still carrying the one-time `token`, OAuth `code`, or attribution
 * params. Every later bare 302 in the chain inherits the query the same way,
 * so no redirect-only route can shed it. Netlify leaves a 200 alone: a
 * navigation gets an HTML page that replaces itself with the clean Location.
