/* ==========================================================================
   KINGSLAND — THE CINEMATIC HERO
   A slow tour of the building: five scenes, each with its own photograph and
   its own words, cross-fading in step.

   THREE DECISIONS THAT MATTER

   1. THE BUTTONS NEVER MOVE. Photographs change, headlines change, the
      call-to-action does not. Nothing is worse than a button sliding out
      from under a thumb mid-tap. Everything above the buttons is stacked in
      a single CSS grid cell, so the block is always as tall as its tallest
      scene and nothing below it ever shifts.

   2. SLOW. Six seconds a scene, 1.6s to cross-fade, and a ken-burns drift
      slow enough that you notice it only if you look for it. Fast carousels
      feel like advertising; slow ones feel like film.

   3. IT STOPS WHEN IT SHOULD. Hidden tab, reduced-motion preference, or a
      visitor who presses pause — the tour holds still and the music stops.
