Solution
n=max(abs(x),abs(z-1))
return y==-2 and(n==2 or x*x<4 and z==-2)and 7 or n==2 and y<-2 and~(x+z+y)&1 or z==-3 and y>-4 and(max(abs(x),abs(y-1))==2 or 2)How it works
Four parts of a hoop packed into one chain.
The rim and bracket are both red at y=-2, so we gate on that first. The rim is the square ring (n==2, Chebyshev distance from the center of the hoop at z=1), and the bracket connects it to the backboard at z=-2. One and 7 covers both.
The net hangs below the rim (y<-2) along the same ring. A 3D checkerboard pattern ~(x+z+y)&1 creates the mesh look, returning 1 (WHITE) for net threads and 0 (empty) for the gaps. The bitwise NOT trick flips parity without needing +1 or parentheses around the sum.
The backboard sits at z=-3 with a white frame and grey fill. Bare true returns WHITE for the frame edge (max==2), and everything inside falls through to or 2 for GREY.
