Strange behaviour on simply including the layers

[hyperknot]

Hi, there is a strange behaviour. I've just set up Panda on a Vite project, everything is default config.

1. If I put @layer reset,base,tokens,recipes; in my index.css, the built file will have exactly this, nothing else.

2. If I include the last one, utilities, such that it looks like this:

@layer reset, base, tokens, recipes, utilities;

Then it'll generate me a 15 KB CSS, file, 700 lines when unminified, which contains every possible variable, those I'm not even using. I mean even things like --colors-zinc-800: #27272a;.

Is there something in utilities which is breaking the tree-shaking? I mean both behaviour seem broken to me, The 4 layers => not including the reset, the 5 layers => including everything, with no tree shaking.
