 These modules are resolved at static import time (before any test runs). Their `vi.mock` factories are served by birpc synchronously during module graph resolution, not after worker teardown.
 
-**Pattern note:** When an overlay or dropdown contains a navigation link (`<a href="…">`), use `e.preventDefault()` + `goto(path)` in the click handler instead of letting the browser follow the `href`. In a vitest-browser Playwright iframe there is no SvelteKit router, so a real navigation tears down the orchestrator iframe and crashes the test run. The `href` attribute should still be present for right-click / open-in-new-tab semantics.
+**Pattern note:** When an overlay or dropdown triggers a navigation action, use `<button type="button">` with an `onclick` handler that calls `goto(path)` — do **not** use `<a href="…">` with `e.preventDefault()`. SvelteKit registers its link interceptor as a capture-phase `document` listener, so it fires before the component's bubble-phase `onclick`. By the time `e.preventDefault()` runs the router has already initiated navigation, which tears down the vitest-browser Playwright orchestrator iframe. A `<button>` carries no `href`, so the capture-phase interceptor never fires. See `NotificationDropdown.svelte` for the canonical example.
