Connect (Extension Auth)
/connect 95%Standalone authentication page for the SideButton Chrome extension. No Header or Footer -- a minimal centered card with email/password form on a light gradient background. After successful login, credentials (email, userCode, mcpUrl) are sent to the extension via three methods (chrome.runtime.sendMessage, window.postMessage, localStorage), then the page shows a success view with green checkmark and auto-closes after 2.5 seconds. The page also displays hardcoded test credentials for Phase 1 development.
