Give deep-scroll editorial pages and presentation layouts a weighted, "velvety" scroll feel — parallax planes drifting at reduced velocity factors (0.3 background / 1.0 foreground), scroll-cued arrivals with a heavy-tailed rest curve (cubic-bezier(0.1, 0.9, 0.2, 1), 800ms+), lerp-smoothed decorative layers, gentle scroll-snap decks — all on top of native scrolling, never replacing it.
