Milestone two opens with touch. Faint chevrons live along the pane's four edges — left and right strips quarter-turn the camera (always), top and bottom stride forward and back (your turn only, through the same commands, cautions, and wall-bounces as the keys). Quiet under a resting eye, brighter under a pointer, generous under a thumb. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
