/* The application's look, translated back to the web it came from.
 *
 * The app styles itself with AtlantaFX's Primer theme — a JavaFX port of
 * GitHub's Primer design system — so the palette below is Primer's, with the
 * lime of the application icon as the brand colour. Light and dark follow
 * the system by default, exactly as the app does; the toggle in the header
 * sets data-theme and wins over the system, so both selector forms appear
 * for every dark rule.
