How do I add a geometry node into a frame without changing the frame?
A frame always adapts to the size of the contained nodes.
If you drag and drop a node into a frame, it will resize accordingly.
However, if you just create a frame and resize it, it will not contain ...

Further python development using Serpens 3 generated code for already existing panel. Buttons added after each script run
The difference is they are registering a panel which is uniquely identified with bl_idname, so registering it twice overwrites the first iteration.

Is it possible to get two Voronoi textures, F1 and F2, to use consistent colors for points?
So let's simplify your idea a little bit, and look at some raw-er data:
Same voronoi, top and bottom. Top is F2 distance - F1 distance. I've marked some centers roughly with empties so we can keep ...

Two identical node setups produce different results
You didn't pack the texture image, but we can see at a glance that your shape has very different UV coordinates than his:
These UV coordinates are going to be used to read the texture. Different UV ...

XOR node for edge matte
There is not an exclusive-or (Xor) function in shader nodes; but you can synthesize an Xor using two nodes. Here is a very contrived example of this:

Map to influence light speed
I think you're asking about changing the threshold of cell shading. In which case, yes, you can modulate that with a texture. The precise things you'd do would depend on how you're cell shading.
