/* ==========================================================================
   Primofort — homepage variant 4: "Sticky rail"
   Same palette, same three typefaces, same content as the live homepage.
   What changes is structure: an asymmetric split hero, and every section
   below built as a sticky left rail (the argument) against a scrolling right
   column (the evidence), instead of one centred stack.
   Token block below is copied verbatim from assets/css/site.css so colour and
   type cannot drift from the main site.
