/*
 note for anyone working on this:

 - Avoid attempts to special-case the first element, and even more so, the last element.
   Such special cases break style reuse.

 - Avoid child queries (queries with spaces in them, like `a b`).
   They cause the engine to check the child `b` then check the parent `a`.
