Import
import { MountedStory } from "@typed/ui/Storybook";Signatures
export interface MountedStory {
readonly canvas: HTMLDivElement;
readonly dispose: () => Promise<void>;
}Why
Stories need access to the actual canvas for assertions and deterministic teardown of a long-lived reactive render.
Ownership and lifetime
The mount owns its private Scope and render fiber. dispose interrupts the
fiber and closes the Scope exactly once; callers own appending/removing the
returned canvas. If the canvas is connected, disposal does not disconnect the
removal observer; removing the canvas is the observer’s cleanup boundary.
Property: canvas
Detached div containing the story’s real rendered DOM.
Property: dispose
Idempotently closes rendering; remove a connected canvas to release its observer.
