StoryContext.userEvent is ReturnType<typeof userEvent.setup> (keyboard(): Promise<void>). UserEvent was picked from the direct API (keyboard(): Promise<System>), so passing a real context to I.init failed typecheck once @testing-library/user-event types resolved; consumers had to cast.

• UserEvent types only clear/click/keyboard/tab/type, taking the setup-instance parameters and returning Promise<unknown>. Both the instance and the direct API are assignable. Still renderer-agnostic, type-only import from the storybook peer.
• test/context.test.ts asserts with expectTypeOf(...).toExtend<StoryContext>() that Storybook's StoryContext and StoryContextForLoaders (with a custom renderer and args, since StepFunction is invariant in them) and a direct-userEvent context are accepted. Without the fix, typecheck reports 3 errors.
• Minor changeset (breaking type change: UserEvent methods return Promise<unknown>, so keyboard() no longer resolves to System). README doesn't mention the type, so it's unchanged.

pnpm run check passes.

📝 Walkthrough

Walkthrough

The UserEvent type now uses method parameters from a userEvent.setup() instance and declares Promise<unknown> returns. Compile-time checks cover Storybook story and loader contexts, including contexts that use the direct userEvent API.
