How do you figure out the right-hand sides (0, 0.2, 1, 1.9)? Just guess random numbers and see what happens, or is there some heuristic for starting the guess?

0 is the border (here in red), 2 is the center of the square, the bigger the parameter, the closer you get towards the middle. Try out a few and see what looks good
(you can also do -2 to 0 to fill in the other half of squares that are currently blank)
Ah, and [-2, 2] is the range of possible values for the sum because [-1, 1] are the possible values of sin (and cos)?
Yup, that's exactly it!
That is a super helpful way to visualise it. I forgot WA can create these 3D Plots. Hell, I forgot 3D visualisations are a thing at all. Thanks for that!
