   Phone: brand row with "Wypróbuj demo", a compact live preview (one vignette at a time, tap = next, dots), then the form card —
   the submit button stays above the fold at 360 × 780. Desktop ≥ 761: paper-2 hero (headline, preview on a stack of sheets with
   pointer tilt + parallax, caption, tabs with a progress rule) beside the form.
   Motion: .is-entering (first show) = staggered entrance; .is-swapping = the card after a mode switch; vignettes cross-fade
   (.is-on / .is-out) and their rows, stamp, bars play when they become active. Transform / opacity only; reduced motion = static. */
