/**
 * The framework's session middleware, except that a request asking for
 * JSON is never remembered as "the previous page".
 *
 * `back()` prefers the Referer header and falls back to the URL the
 * session recorded last. Laravel records every GET not marked as Ajax,
 * and a plain fetch() is not marked. So the notification bell's poll for
 * its unread count became the previous page. Wherever the Referer did not
 * arrive, because a proxy or a browser stripped it, saving any settings
 * form redirected to /notifications/unread-count, and Inertia showed the
 * raw {"count":0} in an error dialog (#1799).
 *
 * The rule is about the request, not about that one route: nothing that
 * asked for JSON is a page anybody goes back to. Inertia visits ask for
 * HTML, so they are recorded exactly as before.
