   Write it Right — "A preview of what you get"
   Horizontal scrollytelling: a tall wrapper pins a full-viewport
   stage while assets/js/preview.js pans the track sideways.
   Panels: 01 Marcus's complete file · 02 gold-standard templates
   · 03 good-enough templates · 04 clips & games (placeholder).
   (04 peace of mind is commented out in the HTML for now; its
   styles below stay so it can be re-enabled.)
   Each panel keeps to its own pv-* class family so a panel can be
   lifted out as standalone HTML later.
