Sorry I forgot this line:

fsc[r_, \[Theta]_, \[CurlyPhi]_] = 
 FromSphericalCoordinates[{r, \[Theta], \[CurlyPhi]}];

I shared the code to display what the chat-enabled notebook is creating, but it's not generating loxodromes like it should. The AI insists that it's producing the desired output, but that's not the case.

I tried running the code, and then turning the new code back into another chat-enabled prompt. After several iterations, I am now to this point, which still has errors:

Improve the following code to represent 4 tubular loxodromes plotted over the surface of two adjacent spheres. The surface area of the four tubular loxodromes equals the surface area of the two spheres. Make sure the tubular loxodromes are centered on the sphere's surface. Make each sphere and each loxodrome a different color. The final image should look like this image: https://sota.aetherwizard.com/images/Book/spin_2.jpg

fsc[r_, \[Theta]_, \[CurlyPhi]_] := {r*Cos[\[Theta]]*Sin[\[CurlyPhi]], r*Sin[\[Theta]]*Sin[\[CurlyPhi]], r*Cos[\[CurlyPhi]]};

sphereRadius = 13;
tubeRadius = sphereRadius^2 / (2 * Pi * sphereRadius);
l = 2 * Pi * sphereRadius * Sqrt[1 + Tan[45 Degree]^2]; (* Length of loxodromes *)

h1[t_] := t;
g1[t_] := t/l;

    fsc[sphereRadius, g1[t], h1[t]], {t, 0, l},

    fsc[sphereRadius, g1[t], -h1[t] + Pi], {t, 0, l},
