/* Demo chrome for the FX Strength Terminal demo: badge, start button, guided tour.
   Uses the app's own CSS variables from styles.css. Everything is prefixed fxd- to stay apart
   from the real app's classes. The badge and start button sit in the terminal header,
   right of the LIVE indicator, so they never cover app content. */
