Well, perhaps by exploiting bugs/shortcomings in PDF and HTML converters. Not by design. However, bugs get fixed, and since the PDF and HTML are generated dynamically, any such hack would be extremely fragile. And while "single source of truth" can help to prevent such malicious discrepancy, it's unlikely that people would try to hack the system this way: what for? Far more likely scenario is unintentional discrepancy, and single source of truth definitely helps to prevent that!
