fp16 VAE produces NaNs on many SD1.5/SDXL checkpoints, yielding black images (often mistaken for NSFW censorship - there is no NSFW filter in the generator). Switch COMFYUI_FLAGS from --fp16-vae to --fp32-vae in .env.example and document the fix in the README. Verified end-to-end: a test generation now produces a real image (mean ~86) instead of black.
