"""The server's half of the shared grammar fixture (core/testdata/grammar.json).

The same cases run against the core (derive.rs) and the web (markdown.ts). A case
that passes in one language and fails in another is a note that changes shape when
it syncs — a checklist that stops being one, or a tag that is a label on the phone
and plain text on the server.
