- Built-in 404. When a visitor hits a URL that doesn't exist on your published playground, FlowFn now serves a clean 404 page (kept out of search) instead of a generic "couldn't load" error.
- Make it yours. A new 404 tab in the playground editor lets you customize the 404 page — edit its HTML/CSS/JS like any other page, or Reset to default to restore the built-in design.
