Consider using asciinema for the demo

Asciinema renders the prompt using native font rendering, which scales to different subpixel layouts, subpixel rendering in general, and high-dpi scenarios.

Hey @namibj I actually recorded some of them before switching to a regular gif: https://asciinema.org/~luizbranco
