   namecheap-cli — project site
   No framework, no build step. Custom properties for theming; the terminal
   blocks stay dark in both themes because that is what a terminal looks like.

   The visual language follows mklaunchd.sh: an off-white page, hairline
   rules instead of heavy borders, one gradient (sky → purple → pink → gold)
   used sparingly for emphasis, and pill buttons.
