/* ============================================================================
   THINKSTV LED — public hero carousel
   ============================================================================

   Layout and movement only. Every colour, size, font and spacing value comes
   from the CMS at runtime as a custom property written by hero.js into a
   generated <style> element. Nothing here should hard-code a brand colour.

   The variables this file expects (all set by hero.js):
     --hero-heading  --hero-subheading  --hero-description
     --hero-btn-*    --hero-max-width   --hero-pad-*
     --hero-radius   --hero-shadow      --hero-icon-*
     --hero-align    --hero-justify     --hero-transition-ms
     --hero-h1-size  --hero-subtitle-size  --hero-body-size  --hero-button-size

   Breakpoints match the rest of the site: 1200 / 1024 / 768 / 480.
