## Where to use it

A bouncy tooltip adds a bit of personality to small hints: explaining the icon buttons of an editor toolbar, labelling a share button or saying “Saved to favorites” above a bookmark icon. It grows out of the button with a small overshoot and a small arrow. It also appears when people reach the button with the keyboard.

Keep the text short, because it stays on a single line. The tooltip uses your page's text color as its background, so it automatically turns dark on light pages and light on dark ones.

## Code

### HTML

```html
<button class="uv-tp">Hover me<span>Saved to favourites</span></button>
```

I want to add the “Bouncy tooltip” block (Tooltips) from AIMRAN Library to my project.

## What it is
A tooltip that pops up above a button with a springy scale, on hover and on keyboard focus.

## Chosen settings
- Main color: #0071e3
- Secondary color: #8ec5ff
- Size: 16px (from 12 to 24px)
- Speed: 1x (from 0.5 to 2x)
- Text: "Saved to favourites"

## What I need
1. Add it to my project with the same look and animation as the reference code: same sizes, colours, radii, shadows, timings and easing.
2. It is built with plain HTML and CSS (the reference wraps it in a React component with its CSS). If my project uses something else (Vue, Svelte, Astro, plain HTML…), translate it without losing any behaviour. If I use Tailwind, turn the styles into classes; if not, keep the CSS in its own file.
3. Expose the settings above as props (or CSS variables) with those values as defaults.
4. Make it work well on phones: nothing that depends only on hover, touch targets of at least 44 px and no overflow on 320 px screens.
5. Make it look right in light and dark mode.
6. Keep it accessible: semantic HTML, roles and aria-* where needed, visible focus and keyboard support.
7. Respect prefers-reduced-motion: with reduced motion, no big animations but the same end result.
