How smoothly two pieces of geometry meet, in the standard notation. C0 means they touch, G1
means tangent directions align, C1 means tangent vectors match, and the G2/C2 and higher grades
add curvature continuity. This is what decides whether a fillet reads as smooth or shows a
visible crease under reflection.
