   单板滑雪的技术 / snowboard track  (Snowboarding Technique — CASI + Park)
   Part of the 运动 group. A technique-only, advanced + freestyle track built
   on CASI's fundamental-movements framework (stance & balance · rotation /
   flexion-extension / edging / fore-aft · turn phases) linearized from one
   engine: you manage EDGE × PRESSURE to turn gravity's fall into a
   controlled arc. Widgets draw the slope, the board, edge/pressure, turn
   phases, jumps and spins procedurally on a .slope-canvas — no images.
