/* ============================================================
   HERO CAROUSEL — Cover-flow style hero slider
   Markup expected (already in index.html):
   <section class="hero-carousel" id="heroCarousel">
     <div class="hero-track" id="heroTrack"></div>
     <div class="hero-dots" id="heroDots"></div>
   </section>
   All slide elements are created dynamically by hero-carousel.js

   Active/side card dimensions below are matched 1:1 to the
   reference implementation (mobile 220x315 / 160x229, tablet
   195x279 / 155x222, desktop 215x308 / 170x243) so sizing and
   the active-vs-side contrast look identical at every breakpoint.
