Align P4 codebase with the Design System in order to unite the Planet 4 product team as well as the P4 community around a common visual language.

It will help reduce design debt, and accelerate the design process, by preventing errors and fixing current inconsistencies across the product.

The P4 design system aims to be the source of truth to keep designers, developers and other collaborators aligned on a consistent product user experience when working on design iterations and building new features.
