/* Kodza — Code Block
   Code to read and copy: a file name, line numbers, lines to look at (data-highlight="4-6"),
   and a monochrome highlighting that works with weight and light rather than colors (keywords
   bold, comments dimmed, strings bright). Copy rolls to Copied. --terminal shows a shell: the
   prompt and the output are left out of what you copy. Languages: js, css, html, shell.
   A long file scrolls inside the block past --kz-code-max-height (none by default).
   Everything is tuned with the --kz-code-* variables. */
