   Scoped to .fls. Brand: neon synthwave (cyan #00f0ff, pink #ff2f9e,
   purple #a855f7 on deep navy), same tokens as optimizer.css (--fro-*).
   Upload step lives in the page flow; pick + paint run as a full screen app.
   Shared Studio components (top bar, buttons, cards, fields, viewport frame,
   rail, upload hero, toasts) live in fmr-studio-ui.css (.fsu-*), loaded first;
   this sheet keeps the Livery-specific layout and widgets.
