Adaptive Fashion E-commerce Hero Banner Pipeline

What we're building A pipeline that composites 2-3 individually-generated model+garment shots into one shared lifestyle scene for an e-commerce hero banner built so each model's outfit is an independent swappable layer, not baked into one generation, so changing what "model 2" wears later doesn't touch anyone else in the image. Problem it solves Multi-person hero banners (the "3 models, 3 outfits, one scene" look every fashion e-commerce homepage uses) can't be generated reliably in one AI call current models garble anatomy and scale when asked to place multiple full figures together. Splitting it into individual generations plus manual composition avoids that failure mode entirely, and as a side effect gives you a genuinely reusable asset: swap one garment, regenerate one layer, done.
