The crosshair moves to a random point over 0.8s on [0.7, 0, 0.3, 1], its spotlight turning to follow, then pulses its radius from 7 to 10.5 and back.
At rest, set in Clerk's own fonts for the check, it matches the card on clerk.com pixel for pixel; hovered, its motion was compared with clerk.com's at the same instants after the pointer arrives.
