/**
 * Real user config file, loaded NATIVELY by the integration (the same
 * `vite.runnerImport("/waku.config")` semantics as waku's own CLI — see
 * packages/frontend-frameworks/src/waku/Waku.ts `loadUserConfigFile`). Both settings here are
 * user-observable and only work if this file is honored:
 *
 * - `rscBase` moves waku's RSC endpoint/payload base from the default `RSC`
 *   to `custom-rsc` (asserted against the SSG payload path in the smoke
 *   test).
 * - the user vite plugin serves a virtual module imported by
 *   `src/pages/config-marker.tsx` — if the file were replaced instead of
 *   merged, the import would not resolve and build/dev would fail outright.
