/* Customer review page — built for one thumb on a phone held one-handed.
 *
 * The rules this layout follows, in case a later change is tempted to break one:
 *
 * 1. One question per screen. A long scrolling form reads as work; a single
 *    question with three fat buttons reads as a tap.
 * 2. Everything you touch lives in the bottom half. The question sits at the
 *    top of the card, the answer controls are pushed to the bottom of it, and
 *    the Next button is in the bar at the very bottom — all inside the arc a
 *    right or left thumb sweeps without the hand shifting grip.
 * 3. Nothing tappable is under 52px, and options are full-width, so the target
 *    is the whole row rather than a small circle at its edge.
 * 4. The page is exactly one viewport tall (100dvh, not 100vh — vh is wrong
 *    while the mobile browser's address bar is showing) so a step never needs
 *    scrolling and the bar never floats over the answers.
 * 5. Single-answer questions advance themselves. The Next button stays for
 *    everything else, so the customer never has to hunt for "how do I go on".
