With TRUSTED_PROXIES unset, bin/entrypoint.sh gives nginx one
set_real_ip_from line for each of 10.0.0.0/8, 172.16.0.0/12 and
192.168.0.0/16, as sneak ruled on 2026-09-22 for every app. A list
replaces them, and set and empty trusts no proxy; each entry is checked
as before. The backend inside the container still trusts only
127.0.0.1/32. README.md, configs/nginx.conf and the comment in
script/frontend-viewport-test say the new default.
