A lavender field. One hairline. One caption. For eight seconds, nothing happens. Then something does — once — and does not happen again.
This is the restraint plate. Where every other lab is a steady-state loop doing the same thing at second three and at minute thirty, this one withholds, delivers a single event, and stops. The piece is the event.
With prefers-reduced-motion, the event arrives on click rather than on a timer — same mark, your timing.
