Reuse _normalize_video_denoised in _sample_const_rf_full (Hybrid CONST/RF path) and sample_funpack_distilled_flow: new normalize_strength / normalize_start_sigma (default 0 = off). Applied to the denoised after rescue/quality-sharpness, video-only, so audio is never touched and the samplers keep AB2/Heun/velocity/rescue. Wired node INPUT_TYPES (appended) -> get_sampler -> Studio _build_one_sampler + JS panels for both. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
