5.4 is actually awful at frontend. Used it to update the hackathon site today, lost 2 hours of time trying to wrangle it. Ended up w/ git checkout and Claude oneshotted the problem. Pwns Claude with anything complex, full design system ESlint plugin in basically one shot.

I told it directly to use DVH/DVH to set max container sizes to fix my issue. It ended up massively overthinking and not even coming close to solving the problem. Was like 20 prompts deep trying to get it to just set a max container size.
