Hover-prefetch fires real fetch requests for route loader chunks; those requests go through the same Playwright route handler that serves mocked modules. An in-flight prefetch landing after iframe teardown can hit the handler with a closed birpc channel, raising an unhandled rejection that exits the run with code 1 even when every individual test was green. Add `src/test-setup.ts` that sets `document.body.dataset.sveltekitPreloadData = 'off'` and wire it via `setupFiles` in both `vite.config.ts` (client project) and `vitest.client-coverage.config.ts` (Istanbul coverage config). Add `src/__meta__/browser-preload-disabled.svelte.test.ts` asserting the setup ran. Zero production impact. Issue #553 secondary trigger.
