The style browser surfaced the REST 401 verbatim, which told people to send
an `Authorization: Bearer` header and pointed at styleref.io/mcp — neither of
which anyone can act on from inside ComfyUI.
- A signed-out lane now renders one actionable row: a Sign in button running
the same browser OAuth flow as the Login node, plus a link to the setup
guide. Headless boxes still get the full instructions in the overlay, since
they cannot just click.
- /styleref/saved and /styleref/my-styles map an API 401 to `signedIn: false`
rather than echoing the message. Expired or revoked stored credentials are
the signed-out state, so the dialog should offer sign-in, not an error.
