The grammar is basically a tree of rules, when you enter a subtree, only the rules for that node are “active”.
This means grammars which matches larger structures of the document are not possible to augment without actually changing the grammar, so that’s your only option for now, i.e. clone the full CSS grammar and just modifiy it, rather than include it. There will be a system for injecting rules into existing grammars without forking them in the future.
