/**
 * Every unit the scenario catalog names resolves in helm's index.
 *
 * The catalog is the vendored `.mms` files in the API
 * (services/api/src/matches/scenarios/) and the library is what helm
 * publishes. Nothing at runtime checks the join — a name the index does not
 * key is just a bare hex — so this does, from the sources on both sides,
 * through the same `candidates` rule the browser resolves with.
 *
 * Needs an index: see `unit-index.mjs`. Run with `npm test`.
