1// Mounts the specimens: MentionsList as a host would hold it, with a small in-memory site standing
2// in for the content kit, and a stand-in router (links inside a specimen change its query in
3// place), so every action can be tried on one page. The kit's intents and words here are a
4// specimen's, not a contract; the real ones live with the kit.
