/* ============================================================
   RESULT BLOCK · Duralis Energy
   Architectural variant — closing callout at the end of each
   numbered section on service pages.

   Intent: technical precision, refined blueprint aesthetic.
   Pure white canvas, hairline rules frame the block top and
   bottom, one tiny green bracket marker (⌐) as sole accent,
   centred caption-scale title. Reads like a signature at the
   foot of an engineering drawing.

   Markup contract (required):
     <section class="result-block" data-reveal
              aria-labelledby="result-block-XX-title">
       <div class="result-block__inner">
         <span class="result-block__eyebrow">The Result</span>
         <h3 class="result-block__title" id="result-block-XX-title">
           …
         </h3>
       </div>
     </section>

   - `data-reveal` → picked up by assets/js/scroll-reveal.js,
     which adds `.is-visible` on viewport entry. No extra JS.
   - The eyebrow label can be any short string ("The Result",
     "Why It Matters", etc.) — only visual.
