v0.10.6L replaces the still-unstable animated rim transition with a one-frame deterministic RIM ESCAPE: low-energy coping contact is moved safely down the bowl and given inward speed, so it cannot hover or chatter at the edge. The halfpipe lip is now exactly flush with world ground (0.00 m) and its collision extension is reduced to a narrow tolerance band. RUNNER_ASCENT now uses corrected upward triangle winding plus a dedicated double-sided ramp material, so the orange riding face is visible from normal play cameras while keeping the flush, non-blocking seam. Balance counter-steer and the guarded Skyline Bonus finish are retained.
