Fixed-width LLM token fonts

Create fonts where each token from popular LLMs occupies equal horizontal space. For developers debugging AI outputs.

Why now

As more developers work directly with tokenized AI outputs, visualization tools are needed.

Debugging LLM tokenization behavior is difficult when tokens render at variable widths in editors and terminals.

A font family where every token from major models (GPT, Claude, etc) displays at fixed width, with clear visual boundaries.

AI developers and researchers would pay for better debugging tools.

Start with support for OpenAI's token set.

Risk is limited to professional AI developers rather than mainstream users.
