// Optional external domain (e.g. "https://app.windmill.dev") used to build
// absolute URLs for user-facing links when the Windmill UI is embedded on a
// different host than the API. Undefined = same-origin (default behavior).
// Intended to be set once at boot by SDK consumers (e.g. windmill-react-sdk),
// before any component that builds links has rendered — there is no
// reactivity, so changing it after mount won't update already-rendered hrefs.
