   Chrome and prose for every page that isn't the landing page:
   the legal notices, 404, and the guides. Colours come from
   assets/tokens.css — never redeclare them here.

   The base is tuned for legal text — 14px in a 680px column,
   because those are reference documents to be scanned. Anything
   carrying an `article` class on <main> opts into wider, larger
   settings meant to actually be read; see the ARTICLE section
