@darius I think about the NHS digital. design standards all the time, where the standard is functionally "your target audience is a fifteen-year-old for whom english is a second language. They're using a 6 year old android phone that's been handed down twice, and they are sitting in an hospital emergency waiting room trying to look up information in the middle of the the most terrifying night they have ever had. Your site must work for that person, at that moment."
