Given that o3 just spun its wheels endlessly trying to correct a CSS issue by suggesting to create a "tailwind.config.X" file despite being given the package JSON which contained a clear reference to Tailwind 4x - I'd say any engineer capable of reading and learning from basic documentation.

For reference, Tailwind 4 will not read in config files by default (which is the older behavior) - the encouraged practice is to configure customizations directly in the CSS file where you import Tailwind itself.
