📄 Description

This adds a CLI arg into asciinema stream:

  -H, --html-head [< <style> * { font-family: monospace; } </style> >]
          Additional content to include in the HTML head in case of streaming with built-in HTTP server

Use-case is to allow quickly add customizations. For example adding custom fonts (e.g. Nerd Fonts):

asciinema stream -s 0.0.0.0:8080 -H '<style>
  @import url(https://cdn.jsdelivr.net/gh/mshaugh/nerdfont-webfonts@v3.3.0/build/firacode-nerd-font.css);
  * {
    font-family: "FiraCode Nerd Font", monospace;
  }
  </style>'

Results in:
