 * Per-port vocabularies — pick lists that the rep team needs to be
 * able to tweak without a code change. Each vocabulary is a JSON
 * array of strings stored in `system_settings` keyed by
 * `(port_id, key)`. The defaults below are the values the CRM
 * shipped with; the admin Vocabularies page lets a port admin
 * override any of them.
 *
 * Consumers should call {@link getVocabulary} to fetch the
 * effective list (port override first, falling back to default).
 * Never hardcode a vocabulary in component code — always read
 * through this module so the admin page is the single source of
 * truth.
