MiniMax H3 Progressive Sampler (staged)

Progressive-resolution sampling for MiniMax H3. Runs early steps on a smaller video latent grid, upscales the x0 estimate at each stage boundary, and finishes at the target resolution. Feed a latent already at the final size.

scheduleSTRING0.5:0.55, 1.0:1.0Comma-separated 'scale:end_percent' stages, e.g. '0.5:0.55, 1.0:1.0'. scale is the spatial latent scale, end_percent is where that stage ends as a fraction of the step count. Must end with '1.0:1.0' so sampling finishes at the target resolution. Use '1.0:1.0' alone as an A/B baseline.
upscale_methodCOMBObicubic5 options: bicubic, bilinear, area, nearest-exact, bislerp
verboseBOOLEANtrueLog per-stage grid size, token count and elapsed seconds.
