httpx

var API = &http.Client{
	Timeout:   30 * time.Second,
	Transport: transport,
}

API is for quick JSON calls (GitHub/HF APIs). 30s overall request budget.

var Download = &http.Client{Transport: transport}

Download is for long-running body streams (model files, release tarballs). No overall request timeout; connect/TLS/response-header bounds still apply, so a hung server fails fast instead of wedging the CLI forever.
