Drop the cloud-styled CTA into the intro under a parachute

Replace the gold pill with a fluffy cloud-shaped button — pill base
plus five absolutely-positioned puffs (three on top, two on the
bottom) all in white-to-pale-blue gradient with subtle inner shadow
to read as 3D.

Cradle the button in a 170px LottieFiles parachute (Elmer Vergara's
"Falling Parcel", licensed under Lottie Simple, hosted in
assets/parachute.lottie at 3.7 KB). The whole stack drops in from
above the viewport over 1.6s with a slight overshoot, much faster
than the boxes in the background video, then the parachute keeps
looping in place.

Mouse parallax dropped from the button — it would fight the entrance
animation. Video parallax stays.
