Open WebUI overwrites node 7's text when the request supplies a
negative_prompt, so the default only takes effect when one isn't
provided — which is the common case for the image-button path since the
chat UI doesn't expose the field. Generic quality terms only (no style
or content restrictions) so the default is safe across SD/SDXL/Flux
swaps and doesn't fight whichever checkpoint is loaded.
The smart_image_gen Tool already had per-style defaults; this only
affects the non-Tool image-gen path.
