Consider reading r/Zig How I configure ghostty.

The following config eases me in from my iTerm2 settings. There's probably a better theme, I didn't look for long.

config

theme = "Builtin Pastel Dark"
font-family = "Roboto Mono for Powerline"
font-thicken = true
window-height = 60
window-width = 120
 
# consider
#copy-on-select = clipboard

Per ghostty terminfo page, if you run into a missing or unsuitable terminal: xterm-ghostty error, you can:

infocmp -x | ssh YOUR-SERVER -- tic -x -

to export the terminfo entry from your host and import it on the remote machine.
