/*
 * The app's screens as a carousel (founder, 2026-10-13: "ek center ma, baki
 * side py 1 1", the rest a swipe away, instead of a wall of tall pictures).
 *
 * Without JavaScript it is a plain row that scrolls sideways and stops on
 * each phone (scroll snap). carousel.js adds the depth: the phone in the
 * middle full size, its neighbours turned and smaller, the rest fading out,
 * plus the arrows, the counter and the group chips. With reduced motion
 * nothing turns or scales; the row still scrolls and the arrows still work.
 *
 * Every phone has one frame size (a 390 x 844 screen); a taller capture shows
 * its top, a shorter one sits on the frame's own colour, and the whole
 * capture opens in the enlarge dialog (app.js).
