Author here. Thank you very much for the kind words!

I'm a product designer and a design engineer and I love tactile interfaces and typography.

My goal was to challenge myself to build this purely by 'describing' the interface to an LLM, without giving it any image references. Being mosly working in Figma / Sketch for the past decade or so, the process was utterly painful and I craved to go back to Figma to polish and correct the interface, but I persevered and described the UI to the LLM and progressively built the UI.

The stack is Next.js / React / Zustand with zundo for undo/redo, Clerk for auth. I also made the LLM write 60-odd unit tests and playwright tests running against production. It was AI-assisted throughout.

chrismorgan's critique below is mostly correct. Thanks a ton! The eyebrow one is a straight bug. Base range 8 to 32 is indefensible. Word spacing shouldn't be a control at all. Those three are getting fixed today.
