/**
 * Headless E2E for the Riprap UI. Targets a *running* uvicorn on
 * 127.0.0.1:7860 — we don't spin up our own server because the live
 * route depends on the FastAPI backend (planner, FSM, SSE, layer
 * endpoints). Static-route tests work against /q/sample which is
 * fully prerendered.
 *
 * Run with `npm run test:e2e` (uvicorn must already be up). The
 * matrix `npm run check:all` will fail loudly if uvicorn isn't on
 * the port — that's the design.
