Mpi P-H3 Sigmas (denoise)
Image-to-image sigmas for P-H3 Image. For a restyle, leave image_1 of the P-H3 conditioning EMPTY: with the picture there the edit conditioning holds it and denoise barely moves. Pruna's LoRA is distilled to 8 steps that crowd near 1.0, so SplitSigmasDenoise gives a knob that does nothing until ~0.8 and repaints above ~0.85. This maps denoise linearly to a start sigma between start_min and start_max and walks `steps` steps down Pruna's own curve from there to 0. Wire into SamplerCustomAdvanced's sigmas.

Inputs (4)
| Name | Type | Default | Description |
|---|---|---|---|
| denoise | FLOAT | 0.500–1 | How much of the input picture is repainted. Linear in the START sigma: 0 starts at start_min, 1 at start_max. |
| steps | INT | 61–32 | Steps from the start sigma down to 0, spread along Pruna's 8-step curve. |
| start_min | FLOAT | 0.6000–1 | Start sigma at denoise 0. Bench: 0.5 is a near copy, 0.6 barely changes the picture. |
| start_max | FLOAT | 0.9800–1 | Start sigma at denoise 1. Bench: 0.98 is a full restyle that keeps only the rough layout; 1.0 = a text-to-image run. |
