Re: [csswg-drafts] Centralize definition for name conflict handling of naming at-rules (#12977)

> _"The last one wins"_ may have been a simplification. For `@function` and `@mixin`, it is _the rule in the stronger cascade layer_, for example.

Yeah, that definition deviates them from the other specs. So CSS Mixins might still refer to the central definition for the term but keep its definition for how to resolve name conflicts.

> Similarly, many specs defining at-rules have to repeat how to handle multiple declarations of the same descriptor, noting that descriptor declarations can have a priority in some contexts.

Right. We might cover this here, as well. Though to me this seems separate enough to be discussed in its own issue. @cdoublev Maybe you can create one for that?
