 *
 *   --bg         page background
 *   --bg-raised  code blocks and the glow behind the page
 *   --fg         body text
 *   --fg-bright  headings, links, commands, emphasis
 *   --fg-dim     prompt, metadata, punctuation
 *   --line       rules and borders
 *   --alert      errors, search hits, strings in code
 *   --glow       halo around bright text ("transparent" turns it off)
