Note

Low Risk
Low risk: UI-only change that forwards additional positioning props and updates Storybook examples, with minimal behavioral impact beyond tooltip placement.

Overview
Tooltip now accepts side and align props (defaulting to top/center) and forwards them to Base UI’s Positioner, allowing callers to control where the popup renders.

Storybook is updated to center the layout and adds new stories demonstrating different align values and side placements.
