Avoid generating counterfeit or misleading representations of Brazilian currency notes, specifically the 100 and 50 Brazilian reais bills. Discourage the creation of images that lack the accurate design elements, colors, and security features found on authentic banknotes. Ensure that the generated illustrations do not resemble or imitate real currency in a manner that could be mistaken for genuine notes. The goal is to create realistic, illustrative depictions for informational or educational purposes, not to produce replicas or counterfeit images of Brazilian currency.
