## Where to use it

The ring drawing around the option feels like circling an answer with a pen, which suits choices with a sense of speed or priority: standard, express or urgent shipping at checkout, the turnaround at an online print shop or the priority of a support ticket. A radio button with an SVG ring, in HTML and CSS.

The two steps, ring first and dot second, take about half a second. That is fine for three or four options but feels slow in a long list. Label each option with the delivery time or the price to make the choice easier.

````text
I want to add the “Drawn ring radio” block (Radio buttons) from AIMRAN Library to my project.

## What it is
A ring traces itself around the chosen option, then the centre dot fills in right after.

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

## 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.
