Find the technique, not the trend.

A staggered reveal with its timeline exposed as a scrubbable value, so stagger stops being a feeling and becomes a number.

One honest global switch — system preference plus user override — that every animation layer already reads.

One persistent marker interpolated between two authored positions, with a cut mode beside it that shows exactly what continuity buys.

One RAF writes --scroll-progress and --scroll-velocity; every atmosphere and stage reads the bus without registering listeners.

Four translucent planes at different parallax depths producing depth with no canvas, no shader, and no main-thread cost.

Asymmetric enter/leave choreography for same-origin navigation, with named chrome that never cross-fades against itself.

The first three seconds and every route change — a threshold that never mounts under reduced motion and never scroll-jacks.
