Can Invisible hide API keys from a PII filter?
Invisible characters (zero-width spaces and similar) are slipped between the letters. The key looks normal on screen but no longer matches a plain pattern. The AI Node removes them first.
Tested by the shapeshifter against a copy of the current AI Node, with fake keys only. See the full coverage board.
