Create the floating toolbar and tooltip interaction from the shared toolbar video:
- Place a frosted floating toolbar in the top-right of a soft application card.
- Use four real icon buttons with a shared circular active surface that slides between icons.
- Show one black rounded tooltip below the active icon with a small top arrow.
- Make the tooltip morph position and width between labels like "More..." and "Use Floating Window".
- Add tactile hover, focus, and active states for every toolbar action.
- Support keyboard arrow movement inside the toolbar and visible focus styling.
- Respect reduced-motion by removing the slide/morph transitions.
