Hiding messages in a deck playing cards

Good stuff. You could get much better bandwidth than this by tokenizing and using something like a Huffman or arithmetic code on token frequencies. As a simple example, if you set your tokens to be all English words - let's say there are between 500k and 1 million - that's about 9-10 bits per word. I am sure you could do much better than this as well

You can get much better than that by taking a well-known LLM model and encoding a series of offsets from the most likely sequence of tokens, especially if you are OK with the message being slightly different.
