   /styles gallery chrome — RWF theme exploration.
   Token-only styling: when the page enters preview mode the SAME rules
   re-render the gallery in the chosen theme (that's the demo). The only
   literal colours here are the per-theme card swatch dots, set inline
   from runtime-resolved tokens by gallery.js.
