v0.4.68

0.4.68

• Add draggable mobile preview and reorder panels (2cbc5e2)
  Introduce a floating, draggable mobile preview with an expand-to-overlay interaction (isExpanded + viewportRef) and a dedicated desktop preview layout. Adjust container classes and add xl ordering (xl:order-1/2/3) to Controls, Preview and Proxy panels so panel order/layout is correct on large screens. Add useRef import and tweak preview animations/constraints. Bump package version to 0.4.68 (package.json/package-lock updated; tsconfig build info regenerated).
