/**
 * Base-URL resolution for the Gemini surfaces that are NOT a single
 * `generateContent` URL: the Interactions API (`/v1beta/interactions`) and the
 * Files API (`/upload/v1beta/files`, `/v1beta/files/<id>`). They live on two
 * different path roots, so one base override (`VCLAW_GEMINI_API_BASE`) covers
 * both and lets a test point a local http server at every route.
 *
 * `VCLAW_GEMINI_API_ENDPOINT` is deliberately NOT read here: that variable is a
 * full `models/<id>:generateContent` URL and keeps driving the static paths.
