/* ============================================================================
   VIDEO COMPONENT

   Embedded video player with hover effects, shimmer animation,
   and play button overlay.

   Purpose: Display promotional or demo videos in an engaging,
   interactive container with modern visual effects.

   Required HTML Structure:

   <div class="video-container">
     <div class="video-placeholder">
       <button class="play-button" aria-label="Play video">
         <i class="fas fa-play"></i>
       </button>
       <div class="video-text">Watch Demo</div>
     </div>
   </div>

   Or with embedded iframe:
   <div class="video-container">
     <iframe src="..." allow="autoplay; encrypted-media" allowfullscreen></iframe>
   </div>

   Dependencies:
   - Font Awesome (for play icon)
   - animations.css (shimmer animation defined here for video only)

   Accessibility:
   - Play button has aria-label
   - Keyboard accessible (focusable button)
   - Sufficient contrast for text overlay

   Features:
   - 16:9 aspect ratio maintained
   - Hover lift and scale effect on container
   - Shimmer effect on placeholder
   - Glowing border on hover
   - Responsive sizing

   Notes:
   - Shimmer animation is local to this component (not in animations.css)
   - Play button centers using absolute positioning + transform
   - On mobile, play button moves slightly up for better ergonomics
