   isoBOLD — TYPOGRAPHY TOKENS
   Two families do all the work:
     • Inter         — display, headings, UI, body
     • JetBrains Mono — eyebrows, doc IDs, coordinates, metadata,
                        spec-strip labels, code
   Weights stay restrained (400–700). Display is tight-tracked;
   mono labels are wide-tracked and usually UPPERCASE.
