// Run with Node's test runner and Playwright on the module path; see README.md.
// A custom provider's Base URL opens on the API it was saved as
// (01huadalang on Discord: 我选 response 保存了然后再打开一会就变成 openai
// 兼容了). A provider with a chat URL beside its Responses one, saved as
// OpenAI Responses, opens on OpenAI Responses, its chat URL under More
// endpoints; one saved before the pick was kept opens on the first API with
// a URL, as it did. OpenAI Responses picked and saved with no URL of its
// own is said in the form, never dropped; with its URL typed, the Save says
// which API the Base URL is. In English and Chinese, Chromium and WebKit.
