Three prompt-syntax rules for WP Prompt Cleaner, run before whitespace so
the existing rules tidy the seams they leave:
- empty_groups drops (), [], ( , ), (:1.2) and groups left empty
- merge_weights folds nested ( ) weights into one group, ComfyUI-style
(((a:1.1):1.2) -> (a:1.32)), and unwraps a weight of 1
- lora_spacing tidies <lora:...> tags and the space around them
Balanced turns on empty groups + LoRA spacing; aggressive adds merge
weights. The negative column follows the same presets.
