/**
 * The vocabularies that range over the concrete primitive classes, one entry
 * per class in each: the tag a class reports to the `tagOf*()` dispatches, and
 * the tag its codec writes to the wire. They are nominally distinct from each
 * other and from the names the classes have in the schema `type` vocabulary,
 * and a class's entry in one need not match its entry in another. Adding a
 * primitive means adding to each, and they sit together so that one visit
 * does it.
 *
 * The schema `type` vocabulary is the one that is elsewhere, in `api.ts`. A
 * pattern compiles against that module, which can import nothing, and the
 * `FabricPrimitive` declaration there names the vocabulary's type.
 *
 * This module imports nothing, so that any module can import it without
 * creating a circular dependency. The classes themselves import it, which is
 * why the set of them, and what derives from it, is in `impl.ts` and not here.
