Do the Loco-MotionLayout: Building animations with MotionLayout

Recreates a complex Dribbble animation using MotionLayout + ConstraintLayout, building MotionScene XML, keyframes and keypositions, and animated vector drawables; shows exact hacks: custom attributes for card radius and shadow colors, transition listener with onTransitionChange to fade a color, and staggered FAB motion paths. It largely works — Pixel 3 hits 60fps; older HTC One M7 sits ~30fps — but limitations remain: no RecyclerView support yet, API28 shadow APIs, and swipe+click handler edge cases.
