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.

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.
