/* ============ DARK HERO ============
   Shared full gradient hero for company/marketing pages (About Us, OEM,
   Become a Distributor, Regulatory Support, country distributor pages).
   Previously each of these pages hand-coded its own copy of this under
   its own class name (hero-about, hero-oem, hero-regulatory...) with
   drifting H1 sizes (56-80px) and fixed-breakpoint resizing instead of
   the smooth clamp() scaling .page-hero and .article-hero already use.
   This is that consolidated into one place.

   Markup:
   <section class="hero-dark">
     <div class="hero-dark-content">
       <span class="hero-dark-eyebrow">Optional label</span>
       <h1>Headline <span>highlighted part</span></h1>
       <p>Supporting copy.</p>
       ...page-specific CTA row/badges here...
     </div>
   </section>

   A page needing a background photo under the gradient (as About Us
   does) can add a ::before with a background-image on its own extra
   class - see aboutus/index.html for the pattern. */
