- Renamed `ResTool32xLTX` to `ResTool64xLTX` and updated DIVISOR to 64 to prevent odd-dimension `ValueError`s when using latent downscale factors of 2.0 (IC-LoRA). - Updated visual node name in `__init__.py` to accurately reflect the 64x divisor behavior to avoid technical debt. - Updated documentation in `README.md` and `README_EN.md` to reflect the rename and explain the downscale compatibility logic.
