/* ============================================================================
   HERO SECTION COMPONENT

   Full-width hero banner with gradient background, animated title,
   subtitle, and call-to-action.

   Purpose: Eye-catching above-the-fold section to communicate value
   proposition and drive user engagement.

   Required HTML Structure:

   <section class="hero">
     <div class="screenshot-collage">
       <!-- Optional: Background screenshot images -->
     </div>
     <div class="container">
       <h1>
         <span class="hero-text-desktop">Your Headline for Desktop</span>
         <span class="hero-text-mobile">Shorter Mobile Headline</span>
       </h1>
       <p>Your compelling subtitle text here.</p>

       <!-- Optional: Video embed -->
       <div class="video-container">
         <!-- Video content -->
       </div>

       <!-- Optional: CTA button -->
       <div class="hero-cta">
         <a href="#" class="cta-button">Get Started</a>
       </div>
     </div>
   </section>

   Dependencies:
   - animations.css (for gradient-shift animation)
   - buttons.css (for .cta-button)
   - video.css (if using video-container)

   Accessibility:
   - Semantic <section> with <h1> for page title
   - Text has sufficient contrast against gradient background
   - Gradient text uses fallback color for older browsers

   Notes:
   - Title has animated gradient effect using gradient-shift animation
   - Screenshot collage background is optional decorative element
   - Mobile/desktop text swap at 950px breakpoint
   - Contains device-specific optimizations for popular phones
     (Note: Could be simplified to standard responsive breakpoints)
