React only. No additional packages.
Render the default export inside a container with a defined height. Its optional active prop stops movement when false. This example works with React 19; Next.js projects can use it as a client component.

Where it works well
Pair a short expressive call to action with a concrete label on an occasional marketing action.
Reduced motion
The first label stays in place; the button still updates its subscribed state.
Things to know
Hover text is a fine-pointer enhancement. The accessible action label remains clear on touch and keyboard.
