Isn’t that detailed in https://github.com/w3c/csswg-drafts/issues/12536#issuecomment-3225776469?

> … we've resolved that all this "stylesheet-level" stuff (custom media, Mixins, etc) are defined "as you parse", so you use whatever definition is available at the moment (and that might change if you see another rule defining the same name later).

Sidenote: Having been AFK for a week and now seeing `@supports --name { … }` it took me a while to decipher. I first read it as “Is the dashed ident --name” supported, whereas it’s “Is the custom condition `--name` supported”? Maybe we need something extra around `--name` in `@supports --name { … }`? Cfr. what @dbaron [said before](https://github.com/w3c/csswg-drafts/issues/12622#issuecomment-3423717048).
