     Caslon is the establishment serif of banking, law and publishing — an
     authoritative voice that reads as considered rather than fashionable.

     Two cuts, each used at the size it was drawn for:
       Display  large headlines; tighter fit, finer hairlines.
       Text     sub-headings and pull quotes; sturdier at reading sizes.
     Inter carries every piece of UI and body text.

     Both Caslon cuts ship a single upright weight (400). Never ask for 500+
     on them, or the browser synthesises a smeared fake bold. Hierarchy comes
     from size, colour and spacing instead.
