/* Star History chart. The scene draws no surface of its own — it stands
   directly on the embed's themed stage — so every color here is either ink or
   a series hue, and the .dark block restates only what has to change.

   The one embed on the page that does not follow the theme picker: it reports
   on the three CLIs rather than demonstrating one, so it stays on the site's
   own light/dark pair and never links cli-theme.css. */
