Default terminal language

default_language controls the redirect for terminal paths without a language prefix. Supported values are:

en, ru, de, es, fr, pt, zh, cn, tr, hu, ja, pl, ko, vi, jp, id, th, fa, ms, it, cs, ro, ar.

The value is normalized to lowercase. Missing and unsupported values fall back to en. For example, with default_language: "de", /sign/in redirects to /de/sign/in, while /en/sign/in is not redirected. Existing query parameters are retained in the redirect URL.
