## Where to use it

PIN dialogs tend to be four empty boxes, and this one feels like the safe in a hotel room. Brushed steel with rivets, round metal keys that sink when pressed, amber dots in a recessed display and a status light that goes red or green. A wrong code shakes the panel and resets it. It works for parental locks, vaults, escape room games and app passcodes.

The main color is the success light and the second one the metal tint. Change the code in the script, and type it with the number keys or Backspace as well as with taps, since the panel listens to the keyboard while it is open.

## 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 “Safe keypad dialog” block (Overlays) from AIMRAN Library to my project.

## What it is
A brushed metal panel with keys that sink, indicator lights and a shake when the code is wrong.

## Chosen settings
- Main color: #22c55e
- Secondary color: #b6b0a8
- Size: 16px (from 12 to 24px)
- Speed: 1x (from 0.5 to 2x)
- Text: "Introduce el código"

## 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.
