you know, maybe understand actual frontend dev issues more deeply before arguing against toolsets you are unfamiliar with. none of your suggestions/generalizations actually address my actual real world issues and rather they are non-issues in modern dev.

the type of apps i'm talking about aren't just a "theme.css", so whatever mythical large app you're talking about that adheres to this rigid css standard while being easy to maintain i'm ready to be proven wrong lol.
