/* ============================================
   SmartML — Complete Stylesheet

   Type scale (strict):
     17px  — meta (cite, role, back-link, copyright, buttons, counters)
     20px  — body (paragraphs, nav, lists, cards, bios)
     24px  — subhead (h3, h4, card-client)
     clamp(28px, 3.5vw, 38px) — h2, quotes
     clamp(40px, 5.5vw, 60px) — h1 (page titles)
     clamp(48px, 11vw, 108px) — display (contact headline)
     clamp(24px, 3vw, 34px)   — hero body (index only)

   Layout: ONE container width. Text measure on
   individual elements, not wrappers.
