/* ═══════════════════════════════════════════════════════════════════
   Connect Mobile — Onboarding 1-slayd (HTML/CSS/JS ko'chirmasi)

   Maket: 430×932 (iPhone Pro Max). Vue versiyasida barcha o'lchamlar
   vw/dvh ga bog'langan — chunki u faqat telefon ekranida ishlaydi.
   Bu yerda o'sha birliklar cqw/cqh (container units) ga o'tkazilgan va
   `.ob-frame` qurilma viewport'i vazifasini bajaradi:
     • telefonda — 100vw × 100dvh (ya'ni cqw === vw, cqh === dvh);
     • desktopda — 430×932 ramka.
   Natijada dizayn ikkala holatda ham maketdagidek, piksel-piksel bir xil.

   Qatorlar: 1fr | sarlavha | matn | CTA | 1fr.
   Chekkadagi 1fr lar matn ustunini vertikal markazlaydi, rasm esa
   1/-1 bo'ylab cho'ziladi. Rasm moslashuvchan (fr) qatorni qamragani
   uchun grid algoritmi uni oraliq qatorlarni kattalashtirishda
   hisobga olmaydi — ya'ni baland rasm sarlavha bilan matnni bir-biridan
   uzoqlashtirib yubormaydi.

   Ikkinchi shart — past, lekin keng oyna (planshet/telefonning yotiq
   holati, kichraytirilgan brauzer oynasi). U yerda bitta ustun ekranga
   sig'maydi va CTA "buklama ostida" qolib ketardi; ikki ustun esa
   bemalol sig'adi. Shuning uchun bu blok yuqoridagi bir ustunli
   qoidalarni ataylab to'liq qaytaradi (margin/text-align va h.k.). */
