/**
 * Browser-TLS-impersonating HTTP client for chatgpt.com.

 * Thin re-export over the shared `tlsClientBase.ts` factory

 * streaming tail-file, proxy resolution, error classes, SSE detection) lives
 * in the base module; this file supplies only ChatGPT-specific config and
 * preserves the original public export surface.
