## Where to use it
Loyalty cards still live in wallets because stamping them feels good. This one keeps the kraft paper, dashed circles and rubber stamps, built with layered gradients and inline SVG cups. Each press drops a stamp with a slight random angle and a squash, and a live counter reads the progress. It suits cafés, bakeries, gyms and app rewards.
The main color is the stamp ink and the button, the second color the card stock. Change the café name and the reward line, or reduce the slots for shorter programs.
## Code
### HTML

{if(k===li.length){k=0;li.forEach(x=>x.classList.remove("new"));draw();return}const x=li[k];k++;draw();x.classList.remove("new");void x.offsetWidth;x.classList.add("new")})
});
```

## Prompt for AI assistants
Paste this into ChatGPT, Claude, Cursor, v0 or Lovable to adapt the block to your stack (Tailwind, Vue, Svelte…):
````text
I want to add the “Coffee loyalty stamp card” block (Cards) from AIMRAN Library to my project.
## What it is
A kraft café card with eight slots: each tap presses an ink stamp and the last one unlocks a free coffee.
## Chosen settings
- Main color: #b5452f
- Secondary color: #ead9bd
- Size: 16px (from 12 to 24px)
- Speed: 1x (from 0.5 to 2x)
- Text: "Tostadero Nube"
## 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.
