/* styles.css is what the dice page adds to the shared theme
   (web/sdk/theme.css, docs/design/ui.md): the roll, the 0..100 scale with its
   win zone and marker, and the target/direction controls in the bet panel.
   The header, the bet panel, the toast, the history, the fairness panel and
   the layout are the theme's; colours, durations and radii are its tokens.
   app.js sets --from/--to on the zone and --x on the marker; the marker's
   600 ms travel (dial.js RollMS) is the transition below. */
