…ons, which first calculates the vector potential and then the curl to ensure a divergence-free magnetic field.
…eed to implement guardrails to ensure the evaluation point is outside the plasma boundary
…s designed to extend flux coordinates beyond plasma boundary. Tiny modification to compute/nabla.
…e difference between the output oof eq.compute(kernel.keys, grid=source_grid,override_grid=True) and override_grid=False is negligible.
…and vector potential calculations. Also, documentation for RPZ transforms.

Progress toward addressing #1154.

The [attached
benchmark](https://github.com/user-attachments/files/21745848/benchmark_partial_sum.zip)
must be ran on `ku/nufft` branch.
250x speed improvement from ~15 seconds to ~50 milliseconds.
The improvement would be more if the FourierZernike basis is padded as
discussed in #1243.
Then we would avoid the 3D spectral to real transform as well as N^2
FFTs of size N.
(Then this computation would likely be in microsecond range).
fixed docstring for compute_magnetic_grid
…er method control

fix to plasma_field that prevents the phi coordinates from being reordered

errors from wrong basis

bug fix

squash this later

squash this too
…rvation that basis='xyz' previously did not work for virtual casing method

If you can merge the base dd/B_plasma into this one, then the comparison will be much cleaner and I can review it again then!
