Every animation in the build, isolated and running. This page renders from motion.css itself, so what you see here is exactly what ships — it cannot drift from the spec. Hover the interaction demos, or hit Trigger to fire them without a mouse. Use Slow motion to study the timing; it scales playback rate, so the relative timings stay true.
The last section is new work, not yet in the build: how the vertical tubes behind the tablet answer an NFC bracelet tap. Seven options plus a composed sequence, all on the same easing curve as everything above. Switch the wall between five and six tubes to see how each one holds up.
