// the two never drift. Derived from the single ModuleDef registry (modules.ts): a module's optional
// `titleKey` is the longer, descriptive tab title (e.g. "Channel manager"), falling back to its
// short nav `labelKey` when the two are the same. Registering a new Page is then one touch (add it
// to MODULES) instead of also editing a switch here.
