   Steps XL — a large expanding-panel presentation for the 3-step
   "how simple" story. One panel open huge (big headline + copy + a live-feel
   UI vignette), the others collapsed to slim teal columns. Click a collapsed
   panel to open it; auto-advances until the visitor interacts. Pair with
   steps-xl.js.
