/* ==========================================================================
   MASTER-UI-ENGINE — Visual lab chrome
   Page rules for showcase/index.html only. The lab is the tool that browses
   the previews, so it keeps its own dark UI: these rules style the command
   palette, the shortcut affordance and the studio entry point. Nothing here
   styles a component, and no component class is redefined.
   Colours come from the lab's own :root ramp in index.html; durations,
   easings and movement distances come from design-tokens/motion/scale.css
   (linked through engine.css).
