[v4] Unnecessary Variables Causing Build Size Increase

[Harshkt214]

I'm encountering an issue with @theme{}. Even though I'm not adding any classes to my project, it's still including unused design tokens in the build, which is increasing the size by approximately 17KB for just the base styles. I've tried removing all design tokens, but this process is time-consuming check here.

Check out this repo Harshkt214/material-theme.
use bun build to create production build.

I believe this is intended at the moment, as per the docs:

Tailwind CSS v4.0 takes all of your design tokens and makes them available as CSS variables by default, so you can reference any value you need at run-time using just CSS.

I think they must have to add automatic remove of unused styles at build time like before, because removing design tokens manually causes error in development time.

What you think? I report it as a bug.
