PGCRT/CRT-Nodes ? reverse-engineered prompt

Build me a ComfyUI custom node pack that helps with real production workflows for images, video, audio, and text.

I want easy nodes for loading and saving files, handling last image or latent, resizing, batch text and image loading, and saving outputs to a chosen path. Include useful prompt helpers like string splitting, replacing, removing extra commas and lines, and simple logic nodes for booleans and triggers. I also want a solid set of image effects and post processing tools, plus helpers for masking, cropping, tiling, and preprocessing.

For generation workflows, please support FLUX, WAN, and LTX style sampling helpers, LoRA loading and merging tools, latent utilities, and a few specialized video nodes like seamless looping and frame selection. Audio tools would be great too, especially previewing, EQ, compressor, stereo conversion, and transcript support if available.

Make it work nicely inside ComfyUI, keep optional features from breaking the whole pack if they are missing, and look up current docs online if you need to.
