/* ---------- 9. the first screen, phones ----------
   Clarity, 7 days, 210 views of this page: 44% of visitors left before 10% of
   it, 70% before 15%. The cause was measurable rather than mysterious - on a
   390px phone the stage alone is 487px tall (aspect-ratio 4/5), and with the
   promo bar, header, hero padding and the thumb strip on top of it the headline
   started around 700px down. A phone shows 650-780px. So the first screen held
   a video and nothing else: no title, no price, no button.

   Two moves, no markup change. Shorten the stage, and reorder the buy box so
   the decision - headline, proof, price, button - happens above the prose. */

   Reordering inside the buy box was not enough on its own: the 56px thumb strip
   and the promo line still stood between the price and the button. .zp-gal has
   no styling of its own, so display:contents lifts the stage and the strip into
   the hero flex directly and lets them be ordered apart - stage, decision,
   strip. On a 390x780 phone that lands the headline at ~443px and the whole
   button above ~690px, inside the first screen. */
