   engaging carousel with 3D perspective effects.

   Required HTML Structure:

   <section class="features-showcase">
     <div class="container">
       <h2 class="section-title">Features Title</h2>
       <p class="section-subtitle">Subtitle text (optional)</p>

       <div class="showcase-container">

           <i class="fas fa-chevron-left"></i>
         </button>

         <div class="showcase-frame">
           <div class="showcase-slides">
             <div class="showcase-slide center">
               <img src="screenshot1.png" alt="Feature 1">
             </div>
             <div class="showcase-slide right">
               <img src="screenshot2.png" alt="Feature 2">
             </div>
             <!-- More slides with classes: far-left, left, center, right, far-right -->
           </div>
         </div>

         <button class="showcase-arrow showcase-arrow-right">
           <i class="fas fa-chevron-right"></i>
         </button>
       </div>

       <div class="showcase-caption">
         <h3 class="feature-name">Feature Name</h3>
         <p class="feature-description">Feature description text</p>
       </div>

       <div class="showcase-indicators">
         <div class="indicator active"></div>
         <div class="indicator"></div>
         <div class="indicator"></div>
       </div>
     </div>
   </section>

   Dependencies:
   - Font Awesome (for arrow icons)
   - JavaScript for carousel navigation logic

   Slide Position Classes:
   - .center        # Active/focused slide (center, full opacity, scale 1)
   - .left          # Left preview (85% scale, rotated, semi-transparent)
   - .right         # Right preview (85% scale, rotated, semi-transparent)
   - .far-left      # Hidden left (opacity 0)
   - .far-right     # Hidden right (opacity 0)

   Accessibility:
   - Arrow buttons should have aria-labels
   - Indicators should be keyboard accessible
   - Images should have descriptive alt text

   Interaction:
   - Desktop: Pause on hover, resume on mouse leave
   - Mobile: Tap center slide to toggle play/pause
   - Both: Click side previews to navigate left/right

   Notes:
   - Uses 3D transforms (perspective, rotateY)
   - Smooth transitions with cubic-bezier easing
   - Auto-rotation every 8 seconds
   - Three responsive breakpoints with static dimensions:
     * Desktop (>1024px): 900px x 500px frame, slides 630px x 450px visible
     * Tablet (769px-1024px): 700px x 450px frame, slides 490px x 405px visible
     * Mobile (≤768px): 240px max-width, 9:16 aspect ratio, slides 180px x 341px visible
   - Device-specific optimizations for iPhone SE

   Mac Screenshot Dimensions (2x Retina):
   - Desktop screenshots: 1260px x 900px
   - Tablet screenshots: 980px x 810px
   - Mobile screenshots: 360px x 682px
