Real glTF samples, live configurator. Pick a colour, swap the finish, drop the lighting: the SKU, price and AR link update in real time.

Six Khronos reference assets, the same files three.js uses to showcase PBR, transmission and IBL. Re-skin the model with a colour swatch, switch finish (matte → polished), drop the scene lighting (studio → sunset → workshop), pick a size. Your shopper would see the same thing on a product page.
