CardGestureLayer class

Gesture disambiguation layer for the morphing card carousel.

Handles the conflict between horizontal carousel swiping and vertical fullscreen morph:

  • Locks direction after an initial threshold (16px).
  • When verticalProgress > 0.2 → horizontal swiping is disabled.
  • When fullscreen → only vertical drag (downward) is allowed.
  • Horizontal drag → carousel index change.
  • Vertical drag → card expansion / collapse.
