I'm not sure it's completely dead.
We use Claude for design of document templates a lot, and whilst we've built a fantastic pipeline for doing that well, asking Claude to then design anything outside of our guardrails isn't effective.
So I could imagine folks prioritising high quality design of all kinds choosing templates that would guide Claude.
I look at a large number of startup websites and it's very clear which ones are using Claude the excessive CAPS headings alone give it away. They look OK but the Claude aesthetic does leave me wondering whether this is a real business or one person using Claude to build a LP.
