One module, prompt_boxes.js, now decides which boxes of a live node take a
prompt and whether each is positive or negative. A prompt box is a
multiline STRING input by the node's ComfyUI definition, not a widget
whose name looks right; its role is its own name (positive / negative) or
the wiring down to a sampler's positive / negative input, not the title.
- Material drops, Prompt Studio, the translator and recipe capture use it;
their name regexes and fallbacks ("any string widget") are gone.
- Prompt Studio's role detection read graph.links[id], which is a Map in
current ComfyUI, so it never followed a link; it uses the module now.
- Material writes call onWidgetChanged(name, ...) as ComfyUI expects.
