/* ---------- 1 Oct (client): every row between the hero and the closing CTA is an inset rounded card on the one paper
   ground, with visible side space and one gap, so a white card next to a lavender or ink one never butts into it
   (docs/review-01oct/cards.md). Colour order: white (Problem) -> deep indigo (How) -> lilac (When) -> white (Both
   sides) -> mist -> indigo banner (Three ways) -> ink (Final) -> lavender (Real payments) -> white (FAQ). The hero
   melts into the paper above the first card; the paper under the last card is where the CTA's flipped banner starts.
   Anything wide inside a card (swipe rows, lanes) runs to the card's edges and is clipped by its corners. */
