# Audience router

`nomadro.com` is split by audience:

| Audience | Destination |
| --- | --- |
| Chinese users (`nomadro_route=zh`, via language/timezone sniff) | Next.js `:4003` |
| English users / default | WordPress `:8088` |
| Googlebot / AdsBot / other crawlers | WordPress (AdSense English surface) |

First HTML visit without a cookie gets a same-origin sniff page that sets `nomadro_route` and reloads.

Detection matches `is-china-user` language + timezone signals (any Chinese language in `navigator.languages` counts).

Router listens on `127.0.0.1:4403`.
