Stance regarding LightningCSS

[NatanLifshitz]

Vite recently added support for LightningCSS, which seems to have some benefits, but does not support a CSS preprocessor.
At around the same time, Mantine started recommending using a CSS preprocessor (in 7.0.0).

I'm wondering what is the current best practice regarding this and if there is any plan to address this incompatibility. Currently the options are:

• Do not use postcss-preset-mantine, which is not recommended.
• Do not use LightningCSS, which has a performance impact both on the dev front and in the production front.

You can use any tools for styling, it is not required to use mantine PostCSS preset – it is just a set of functions and mixins. You can write pure css, although it will be 1.5x – 2x of code that you will need to write if you need to handle both light and dark color schemes in your application.
