/**
 * An Interaction represents transient UI state for a component, typically separate from the
 * actual 'business' state that a component may control. For example, a button typically fires an
 * `onClick` callback when the button is pressed and released, but it may still want to show
 * that it is being pressed before this callback is fired. This transient state is represented by
 * an Interaction, in this case [PressInteraction.Press]. Using Interactions allows you to build
 * components that respond to these transient, component-owned state changes.
 *
 * To emit / observe current Interactions, see [MutableInteractionSource], which represents a
 * stream of Interactions present for a given component.
