/* Build Your AI. Page styles on top of gen.css (round nine, October 17, 2026).
   Desktop: the question on the left with a sparkle progress row on top, the plan filling in on the right.
   Below 1100 px: one column. The plan becomes a bar at the foot of the screen that opens.
   Orange is a fill only: a picked answer's sparkle, a finished step, and the main button. */
