Option — Crossfade Slideshow

Slideshow thumbnail vs. static image

All 3 cards use the CSS crossfade — 5 screens, 25s loop each, staggered so they're never in sync.


Option — Two-up + Zoom (mobile screens)

Mobile UI — two screens, then expand

Each pair of portrait screens is shown side by side, then slowly zooms into one for a closer look before crossfading to the next pair.
