## Where to use it
Plant shops, garden centres and nature guides can filter by leaf shape, and a herbarium shows each shape better than a word. Six taped paper sheets hold pressed leaves drawn in SVG, from needle to compound. Ticking one straightens the sheet, brings the dried leaf back to fresh green and draws a pencil loop around its label with a stroke animation.
The first colour is the fresh green and the second the paper. Swap the leaves for flowers, seeds or mushrooms by editing the SVG paths, and keep the labels short so the pencil loop wraps them neatly.

````text
I want to add the “Herbarium leaf shape filter” block (Filters) from AIMRAN Library to my project.
## What it is
Herbarium sheets with pressed leaves: tick a shape and the leaf turns green again while its name gets circled in pencil.
## Chosen settings
- Main color: #3f8f46
- Secondary color: #f6f0de
- Size: 16px (from 12 to 24px)
- Speed: 1x (from 0.5 to 2x)
- Text: "Forma de la hoja"
## 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.
