## Overview

This repository is a ComfyUI custom-node plugin for learned Wan latent resizing. The principal workflow takes an image or video latent through a version-specific node, loads a matching learned model, and returns a resized latent for downstream decoding or refinement. The README documents both Wan versions, up/downscaling, arbitrary scale factors, and image/video latent support. Source excerpts show node registration, model loading, and resizing internals; Wan2.2 details are partial, so uncertain internal wiring is omitted.
