// the source must be a real wreq-js BrowserProfile. PR #5237 set them to
// "chrome_149", which does not exist in wreq-js 2.3.1 (the union tops out at
// chrome_147) — the native layer then produced a degenerate fingerprint and the
// Codex Responses WebSocket upstream rejected the upgrade ("Invalid JSON body").
// This test reads the supported set straight from the installed wreq-js type
// definitions, so it stays correct as the dependency is upgraded.
