 * built `dist/` is embedded in the Go binary and served by the same origin
 * as new-api (so /api/* and /v1/* work via session cookies, no CORS).
 *
 * In dev, you typically run `npm run dev` here and the Vite server proxies
 * `/api`, `/mj`, `/pg` to new-api. We default to http://localhost:3000
 * (new-api dev backend), but you can override with VITE_NEWAPI_BASE.
