Flume MVP0
Minimal first-party chat.
This page is the thinnest possible web surface for the new stack: Better Auth session, edge-to-runtime turn handoff, and a single mobile-first conversation pane.
Session
Signed-in state comes from Better Auth on the edge worker.
Checking session
Email sign in
Send one email that includes both the one-time code and the magic sign-in link.
Chat
Authenticated requests proxy from edge to runtime using the current Flume session.
