I thought this was some crazy CSS syntax I've never seen before:

    background: @shaders(
      fragment { }
      vertex { }
      texture { }
    );

Searching around just leads back to this blog though [0]. It would be amazing if this was real syntax, but I guess security reasons would probably make it a no-go for general use.

Indeed, there was an old CSS Shaders feature (in Chrome, behind a flag) behind from way back around 2013 [1]. Unclear if there's been any development since.
