Last time I found a paper in Graphics Gems titled Solving the Nearest-Point-on-Curve Problem, which transforms the problem into a Bernstein polynomial form. Then an exact solution can be obtained using A Bézier Curve-Based Root-Finder. This is my implementation [1], but it's not very robust for high-degree cases.
Better if it allowed single-tool installs instead of the whole suite.

Don't have access to read the code, but I think ideally there should be only one instance created at startup, right?

If VPNs don't work for you, I recommend using an anti-censorship tool with an obfuscation protocol like v2ray which is commonly used in China.

I think it's more the waste of space in it all. Encoding data in base64 increases the length by 33%. So base64-encoding twice will blow it up by 33% of the original data and then again 33% of the encoded data, making 69% in total. And that's before adding JSON to the mix...
And before "space is cheap": JWT is used in contexts where space is generally not cheap, such as in HTTP headers.
Not exactly - encoding it twice increases by 4/3 * 4/3 - 1 = 7/9, which is about 77.78% more than the original.

The spiral looks unnatural, why not do it like this: https://imgur.com/a/e25fDvc ?
This was my first instinct as well, which makes sure numbers are adjacent. OP also mentioned this variant as lucidBrot/hexgridspiral in the older post.
