How this animation works
Pointer-driven before/after wipe.
- Trigger
- hover — cursor position along one axis sets the wipe line.
- Motion
- two full-bleed images are stacked; a soft-feathered gradient mask keyed to the pointer wipes the after layer across the before (left-right in some variants, top-bottom in others), a glowing seam line rides the wipe edge, and a custom themed cursor sells the metaphor; the reveal retracts on pointer leave.
