/*
  Conversant — site styles, design v2 ("navy cloth, gold stamping")

  Ivory pages, near-black ink, and the navy and gold of the crescent logo, used like a
  clothbound book: navy bands, gold only for ornaments and small stamped details.
  Dark mode is a night sky: blue-black with gold.
  Type: Cormorant Garamond for display, EB Garamond for reading, both self-hosted under the
  SIL Open Font License (see /assets/fonts/). Design history: DESIGN_HISTORY.md.
