The run now starts outside the gym, first person and facing the doors, and nothing walks you in: progress is how far along the carpet you are, which still pulls the camera from first into third person, and crossing the doorway ends it. The eyes follow where you face. Wandering 1600 units off or dawdling past 30 s hands back the normal camera. Chalk: a stroke's start only advances when a segment lands — moving it on a skipped short segment left gaps whenever the chalk moved slowly — and a stroke is at least ~1.6 texels of the pool surface wide so it does not break into dots on the console's coarser texture. Metal samples the pool marks linearly instead of as texel blocks. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
