stable-diffusion-webui-on

Port a new text-to-image model architecture (a new DiT/UNet base model that Forge/A1111 or diffusers cannot load natively) into this project — first as a standalone inference pipeline to verify correctness, then as a native Forge diffusion engine so the checkpoint loads and generates in the WebUI/API. Use when asked to "support / 兼容 / 整合 a new model architecture", run a model whose baseModel is unfamiliar (e.g. a Cosmos/Lumina/Qwen-Image/Z-Image/Anima-style DiT), or reproduce a ComfyUI-only model in plain diffusers/torch.

Write or adapt a Forge / A1111 (Stable-Diffusion-WebUI) extension — a script under extensions/ that adds UI and hooks into the generation pipeline (callbacks, attention/UNet monkeypatching). Use when asked to build a new extension, modify one like the regional prompter, or make an attention-based extension work across model architectures (UNet vs DiT).
