/* ==========================================================================
   SAJ Dental Clinic — "Our Story / From Consultation to Confident Smile"
   Scope: everything lives under .smile-story (and .story-scene inside it).

   Layouts
   - Panel layout  (min-width 992px AND min-height 620px): intro + the
     arched panels side by side. JS pins it and scrubs through the scenes.
       >= 1200px  intro on the left (~30%), panels on the right
       992–1199px intro across the top, panels full width below
   - Vertical layout (everything else: iPad portrait, phones, short
     screens): one scene after another with a drawn rail on the left.
   Without JS (or with reduced motion) both layouts are fully readable.
   ========================================================================== */
