// Railway serves this through `npm start`, which is `vite preview`. Vite's
// preview server answers any Host it was not told about with 403 -- the
// DNS-rebinding guard that arrived in 6.0.9 and is on by default. The
// platform's own probe comes in as `healthcheck.railway.app`, so every
// deployment built cleanly, started, and then failed its healthcheck five
// times in thirty seconds. Four merges on 2026-09-21 never reached a running
// replica, and the build log said SUCCESS above the failure each time.
//
// A leading dot allows a domain and every subdomain, so one entry covers both
// the probe and the generated `*.up.railway.app` service domain -- neither of
// which is written down anywhere else, and the generated one can be reissued.
// The guard stays on for every other Host: `allowedHosts: true` would switch
// it off entirely, which is more than this failure asks for.
