I've removed the wood selection boxes from the 3D model viewer area. Now the wood selection only appears in the configuration panel below the 3D model, making the 3D viewer cleaner and less cluttered. Users can scroll down to see the full configuration options.

I've updated the leather selection to display as hexagonal color swatches instead of rectangular buttons. Each leather option now shows a hexagon shape filled with the leather color, with a white border when selected and a checkmark indicator. The leather name appears below each hexagon, matching the visual style of the wood selector but with the distinctive hexagonal shape that reflects the Rokkakkei brand identity.
