/* ================================================================
   OMNIARCH — styles.css
   Reference build for Webflow developer handoff.

   FONT NOTE FOR WEBFLOW DEV:
   Replace the primary font stack below with "Basil Grotesk" once
   the custom font is loaded via Webflow's font uploader or a
   licensed CDN. The fallback stack ('Helvetica Neue', Helvetica,
   Arial, sans-serif) is a geometric sans that reads similarly.
   CURRENT INTERIM FONT: 'DM Sans' (Google Fonts) — closest free
   match to Basil Grotesk. Swap for Basil Grotesk in Webflow.

   The secondary serif font (Times New Roman) is used ONLY in the
   #commandment section and requires no substitution unless the
   brand specifies an alternative.
