I don't understand how React is foundational for Claude Code. You can render that model outputs with anything and it would be just as transformational

Ha, ouais. Je vais m'abstenir de tout commentaire déplacé. Le terminal de Claude Code, c'est du React "traduit" en ASCII a la volée, ce qui causait le bug de flickering. Si, tiens, finalement, faut que ça sorte : c'est complément con comme stack.

Hey! As someone completely outside of programming who's studying right now just to better understand what Claude Code creates... This is definitely an issue on its end. Many of the errors in the code it generated had to do with TypeScript when I looked into them.
