### Welcome!

- [x] Yes, I've searched similar issues on [GitHub](https://github.com/traefik/faency/issues) and didn't find any.

## Description

Breakpoints currently used in faency is not aligned with radix nor with what we apply on other projects.

Set the breakpoints used in this project to be inline with [radix breakpoints](https://www.radix-ui.com/themes/docs/theme/breakpoints).
