// Run with Node's test runner and Playwright on the module path; see README.md.
// Share on local network in a container (莫 on Discord: magpie in Docker on
// a NAS showed the container's own 172.17.x address): the addresses magpie
// finds for itself there are the container's, which other devices can't
// reach. Served over the network (magpie web), the page offers the host it
// was opened at, on the gateway's port, and says so; opened at localhost it
// keeps the container's addresses but says they are the container's own
// and to set MAGPIE_PUBLIC_URL. Outside a container nothing changes. The
// OpenAI/Anthropic switch keeps the host and moves nothing. English and
// Chinese, Chromium and WebKit; no backend, the API is faked here.
