- Extract makeFakePdfjsLib / makeFakeLibLoader to testHelpers.ts — single
source of truth used by both PdfViewer.svelte.test.ts and
usePdfRenderer.svelte.test.ts; removes the diverging-fidelity DRY violation
flagged by @felixbrandt and @saraholt in the PR review
- Add 'loadDocument sets error and loading=false when getDocument().promise
rejects' test to usePdfRenderer.svelte.test.ts — closes the error-path gap
flagged by @felixbrandt and @saraholt
- Replace toBeInTheDocument() with toBeVisible() in the three absorbed
spec-file tests — uniform assertion style across the loaded-state describe
block, as flagged by @felixbrandt

Five tests in usePdfRenderer.svelte.test.ts called createPdfRenderer() without
a libLoader, causing init() to dynamically import pdfjs-dist in the browser.
Every dynamic import goes through Playwright's route handler, which calls
resolveManualMock via birpc to check for mocks. If the RPC closes during
teardown while one of these imports is in flight, the birpc race fires —
even though pdfjs-dist was never explicitly vi.mock()-ed.
Replace all bare createPdfRenderer() calls that invoke init() with
createPdfRenderer(makeFakeLibLoader()), identical to the pattern already
used in PdfViewer.svelte.test.ts. No real module loads, no route-handler
calls, no birpc exposure.
