/* =====================================================================
   Alvin marketing design system (loaded after each page's inline styles)

   One file carries the tokens, type scale, header, footer, buttons, cards
   and frames for every marketing page: the homepage, trade pages, pricing,
   about, security, privacy, terms, pilot, 404 and the articles. Page CSS
   inline in each source keeps layout specifics; this file wins on look.

   Type: Inter 4 (self-hosted, SIL OFL, fonts/OFL.txt). It carries an
   optical-size axis, so headings set at display sizes get the Inter Display
   cut automatically.
