## Where to use it

A notification bell animation makes new activity hard to miss without a loud banner. Put it in the header of a dashboard, a social app or an online course platform. The bell swings with real spring physics, the clapper follows a beat late, two small waves appear at the sides and the red badge rolls to the new number.

In the demo every tap adds one, but in your app the shake should fire when a notification arrives, and only then. Never loop it. The badge caps at 99+, and you can set how many unread items it starts with.

````text
I want to add the “Shaking notification bell” block (Microinteractions) from AIMRAN Library to my project.

## What it is
Tap the bell: it swings on a spring, the clapper lags behind, two small waves appear and the counter rolls up.

## Chosen settings
- Color: #ff453a
- Unread: 3 (from 0 to 20)

## 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 React + TypeScript, with framer-motion for the animation and lucide-react for the icons. 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.
