/* family.css — the shared frame of the .pro family (dipl.pro · corp.pro, and the
   shape locintel.pro already has). Byte-identical in every property; a property
   changes how it looks ONLY through the tokens in its own site.css.

   What is shared (the frame): page anatomy, the apparatus voice (IBM Plex Mono),
   the provenance chips, the fact row, the header skeleton, the colophon.
   What is not (the room): paper, ink, accent, display face, header ground.

   Contract: /canonical/projects/_shared/DESIGN.md. AAA by arithmetic: every text
   token in site.css is declared with its ratio, and nothing here uses opacity
   on text (NAISU-DNA §1.10–11). */
