Diff mode is the hyper-analytical mental state where you're actively scanning for what changed, what's off, or what's being hidden — like your brain switched from passive reception to active comparison. Someone in diff mode is not just watching; they're auditing. They pause videos to read background text, screenshot consecutive frames to compare expressions, and bring a forensic energy to content that was never designed to be forensically examined. Diff mode is the state that fuels conspiracy rabbit holes, fandom theories, and celebrity gossip deep dives — it's the gear your brain shifts into when something doesn't add up.
