Implements per-block DiT activation steering as an alternative to textual inversion. Extractor runs frozen generator on dataset with BJ vs empty conditions, records mean hidden-state delta per block, saves [hidden_dim] vectors (seq-averaged so they broadcast to any inference duration). Loader reads the bundle. Sampler registers forward hooks during the ODE that add strength × vec to each block output, cleaned up in a finally block.
