   RUTTENS+ · style-v6.css
   Radical-simplification build · rev 3 · 2026-08-09
   rev 3 adds: nav dropdown CSS (menu rendered expanded without it)
              + mobile nav (links were hidden with no hamburger)
   Additive — does NOT touch css/style.css. index-v6.html only.

   TOKENS INHERITED VERBATIM FROM THE LIVE SITE (css/style.css, v5)
   so v6 sits seamlessly next to about.html / solutions.html / etc:
     --sky #37B5FF · --radius 8px · --max-w 1100px · --border #E5E7EB
     --card #F8F9FA · --grey-mid #444 · --grey-light #6B7280
     h1/h2 = Oswald 700 uppercase, line-height 1.05, letter-spacing .01em
     .btn-primary = sky background, WHITE text
     nav height 72px · logo 80px

   v6 changes ONLY scale and rhythm, never the brand:
     bigger display sizes, deeper vertical bays, fewer elements.
