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.
