/* ===== Custom Theme Override (showcase SVG only) =====
   The shapes have no colours in the HTML, so adding the class
   "custom-theme" to the large SVG lets these rules replace the
   red/blue/white palette. They are more specific than the primary
   rules above (class + class), so they win. Autumn palette:
   amber ring, dark brown bar, cream lettering. */
