// The e2e suite drives the *real* app in a browser — its reason for existing is
// the class of interactive canvas/reactivity bug that "should work by reasoning"
// review keeps missing (see DESIGN.md's "reasoning-only guarantee" note).
//
// The dev server is pointed at a committed, read-only fixture store
// (`e2e/fixtures/storage`) rather than the developer's own `./workflows`, so the
// tests are hermetic and never depend on or mutate ambient on-disk data. A
// dedicated port keeps it clear of a `npm run dev` already running on 5173.
