qwen-image-2512-sd — Qwen-Image-2512 + Lightning 8-step, curated for Enclave's sdcpp backend

Component-layout volume for enclave.host image generation: the Qwen-Image-2512 transformer with the lightx2v Lightning 8-step distillation LoRA merged into the weights, quantized to Q8_0 by the same stable-diffusion.cpp revision the fleet serves with. Generates in 8 steps at cfg 1.0.

~34 GB peak VRAM at 1024px with tiled VAE decode. Component filenames are generic on purpose: Enclave's ENCLAVE_SD_*_FILE envs are node-global, so every SD volume on a node shares the same relative names.
