  </div>
  <div class="w-full md:w-1/2 space-y-3 text-left">
    <h3 class="text-lg font-bold text-slate-900 dark:text-white">1. Interior Natural Light Analysis</h3>
    <p class="text-sm text-slate-600 dark:text-slate-300 leading-relaxed">
      Shadow Slice makes ceilings and upper walls transparent to the camera while keeping them completely solid to sunlight. Look inside and analyze realistic natural light distribution throughout the entire floor plan.
    </p>
  </div>
</div>

<!-- Use Case 2 -->
<div class="border border-slate-200 dark:border-slate-800 rounded-2xl p-6 bg-white dark:bg-slate-900 shadow-sm flex flex-col md:flex-row gap-6 items-center">

  <div class="w-full md:w-1/2 space-y-3 text-left">

    <p class="text-sm text-slate-600 dark:text-slate-300 leading-relaxed">
      Traditional section planes let sunlight flood in from the cut plane, completely ruining interior shadow accuracy. Shadow Slice automatically compensates for the removed section, keeping shadow casting 100% physically accurate.
