/**
 * Auto-executing popup callback handler
 *
 * This module automatically handles OAuth popup callbacks when imported.
 * Use this in your callback page instead of manually creating callback.html:
 *
 * Option 1: Import in your callback page (React/Next.js/Vue)
 * ```tsx
 * // app/callback/page.tsx or pages/callback.tsx
 * import '@authway/client/popup-callback'
 * ```
 *
 * Option 2: Add as a script tag
 * ```html
 * <script src="https://unpkg.com/@authway/client/dist/popup-callback.js"></script>
 * ```
 *
 * This will:
 * 1. Detect if the page is running in a popup with OAuth params
 * 2. Send the auth result to the parent window via postMessage
 * 3. Close the popup automatically
 * 4. If not in popup mode, do nothing (let your app handle redirect flow)
