Headline: "Polaris—unified and for the web"

The work:
- Align components across multiple teams w focus on web
- Extremely light "in-house" framework

- Docs, templates, CLI
- AI, MCP
- "Polaris"

So much more to come.

Lots of things learned, lots of fun edge cases discovered (hello moving web components to iFrames in Firefox)

Been jamming on these interesting iframe and custom element issues this week. Important if you are building a custom element framework.
