## Terminal theme family

The optional `public/themes/terminal-amber.css`, `terminal-green.css`, `terminal-cyan.css`, and `terminal-magenta.css` themes are visually inspired by [hugo-theme-terminal](https://github.com/panr/hugo-theme-terminal).

Terminal loads [Fira Code](https://github.com/tonsky/FiraCode) from Google Fonts at runtime for the monospace face. Fira Code is not vendored in this repository; if the remote stylesheet is unavailable, the theme falls back to system monospace fonts.
