Smaller code is good for wasm.
The url I want to encode is like this:
https://bestia.dev/mem6/#p04.1234
There is a hash symbol here so I cannot use the alphanumeric mode.
I must use the byte mode.
There are 33 characters. It means there is some free space for future uses.
The smallest QR code for that is:

The code is written by treeman. I just removed all the variants I don't need.
