Nano Banana has no negative_prompt — describe positively (“an empty, deserted street”, not “no cars”). Naming what you don’t want can summon it into the frame.
There is no negative prompt on this family; write exclusions as positive constraints.
Weight syntax such as (word:1.3) is ignored; it only wastes prompt space.
Keep to at most 5 distinct characters in one prompt.
