The Button, a page per layer

The Button's page had grown to about 35,000 tokens, so finding your way back to one section meant a long scroll. It's now an Overview, with the playground, the facts at a glance, the reference implementation and the sources, and a page for each layer, all under Button in the sidebar.

Improved

• The User Interface, User Experience, Developer Experience and Agentic Experience sections each have a page of their own, with the layer's rules and, where it has any, the questions it answers, and the Overview's introduction links each one from a card.
• In the sidebar, Button links to its Overview, and the arrow beside it opens and closes the list of its pages, the Overview and its layers, which stays open while you read them.
• Links to the Button's sections from before the split, like one to its loading state, still take you to the right section on its new page.
• Agents still read the Button as one page, as before: /raw/docs/components/button.md, its contract and the MCP server serve it whole.
