- Hide OS crosshair and drawn crosshair when cursor is over ViewCube area - Enhanced hover glow in WGSL shader (blue tint + brightness boost) - Fixed region_centroids() Y-axis sign for all FRONT/BACK-related regions - Swapped corner geometry assignments (TPF↔TBK, BTF↔BBK) to match intended FRONT/BACK semantics (sy=-1 = FRONT, sy=+1 = BACK) - Corrected all snap_angles: yaw_pitch_to_quat(0,0) places eye at -Y (FRONT view), so FRONT=0 and BACK=PI — cascaded through edges/corners Co-Authored-By: Claude Sonnet 4.6 <[email protected]>
