  description: >-
    Hidden Chicago 18 component base. Carries only the options-level rules
    shared identically by the CMOS author-date and notes heads

    multilingual). Never rendered or discovered directly — both heads
    extend it. Rendered order stays per-style; see csl26-40n4.
options:
  multilingual: romanized-translated
