# Safe Diffusion Guidance (SDG)

Custom Diffusers pipeline that applies a mid-UNet safety classifier as guidance during denoising.
- Plug-and-play: works with any Stable Diffusion checkpoint (e.g., SD 1.5).
- No retraining needed; classifier runs on mid-UNet features.
- Tunable: `safety_scale`, `mid_fraction`, `safe_class_index`.
