 - Fixed "No API key configured" showing after signing out — now correctly shows "Not signed in" with a prompt to sign in
 - Added `/api/organizations` as a final fallback for org ID resolution when the bootstrap API response doesn't include it
 - Fixed usage data not loading — API requests now include required browser-like headers (Origin, Referer, User-Agent)
-- Fixed sign-in detection and cookie handling for accounts whose session cookies are on the `anthropic.com` domain rather than `claude.ai`
 - Fixed Settings incorrectly showing "Signed in" after a failed refresh — sign-in state now resets when authentication fails
+- Rewrote login detection to use the WebView's own fetch call instead of inspecting cookie domains — correctly detects auth regardless of which domain the session token is stored on
+- Fixed API requests not including session cookies — now sends all cookies from the app's WebView store rather than filtering by domain
