Ice Skating Patterns (2D)

This top-down companion swaps the 3D scene for a plain overhead rink so the mechanics driving a skater's path are easier to read: push power adds thrust, ice friction bleeds speed away as Coulomb drag, and the blade's edge-lean angle sets a real centripetal turn radius (r = v²/(g·tanθ)) — carve harder and the turn tightens, glide flat and the skater drifts straight, tracing a fading pattern into the ice as speed and lean change.
