/* ==========================================================================
   Mobile fixes (added — see commit notes)
   1) Hide SEO-only marketing copy on small screens. It stays in the HTML
      for search engines/crawlers, it's just visually hidden here so it
      doesn't clutter the phone layout.
   2) Extra small-phone sizing pass beyond the existing 768px breakpoint.
   3) Touch devices don't have real hover — neutralize the hover-only
      transform/glow effects there so buttons/cards don't look "stuck" or
      lit up after a tap. :active supplies tap feedback instead.
   4) Visual feedback + touch-action for the touch drag-and-drop shim in
      scripts/script.js (native HTML5 drag-and-drop does not fire on touch
      devices, so the workout-timeline builder needed a touch equivalent).
