/* OGDC — Typography tokens
   One typeface, used with discipline: DM Sans. The weights do the work.
   Black 900 → logo · big numerals
   Bold  700 → headlines · eyebrows · labels
   Medium 500 → captions · fine print · UI
   Regular 400 → body copy · paragraphs
   Casing: sentence case for headlines & body; tracked UPPERCASE for
   short eyebrows/labels ONLY — never all-caps sentences. */
