   Display: Source Serif 4, weight 600
   Body and utility: Inter
   Locked 4 October 2026. Pairing E.

   Two families only. Inter carries body, labels and tabular figures, so no
   third utility face is needed; Inter has tabular numerals built in.

   Fallbacks matter: most client files go out as PDF, but decks and sheets
   occasionally go out editable. The stacks below degrade rather than break. */
