 * COMPLETE YOUTUBE STREAMING SOLUTION FOR REACT NATIVE
 * ============================================================================
 *
 * This file contains EVERYTHING needed to stream high-quality audio from YouTube Music
 * in a React Native application, bypassing age restrictions and region blocks.
 *
 * ----------------------------------------------------------------------------
 * 1. THE PROBLEM
 * ----------------------------------------------------------------------------
 * YouTube URLs for music (especially regional content like Indian songs) are often
 * "protected" (indicated by `txp=5532534`). These URLs return `403 Forbidden`
 * if accessed directly by browsers, VLC, or standard fetch requests because they
 * require a specific User-Agent header to prove they are coming from a valid client.
 *
 * ----------------------------------------------------------------------------
 * 2. THE SOLUTION
 * ----------------------------------------------------------------------------
 * We use the InnerTube API with the `ANDROID` client and specific authentication
 * cookies. This generates a direct streaming URL.
 *
 * CRITICAL STEP: When playing this URL in `react-native-track-player`, you MUST
 * pass the `User-Agent` header. This makes the player look like the official
 * YouTube Android app, allowing the stream to play.
 *
 * ----------------------------------------------------------------------------
 * 3. INTEGRATION GUIDE (Copy this into your React Native App)
 * ----------------------------------------------------------------------------
 *
 * // A. Import this module
 * import { getStreamingUrl } from './CompleteYouTubeStreaming';
 * import TrackPlayer from 'react-native-track-player';
 *
 * // B. Function to play a song
 * async function playYouTubeSong(videoId) {
 *   try {
 *     *
 *     // 1. Get the URL and headers from this module
 *     const { url, headers, details } = await getStreamingUrl(videoId);
 *
 *     *
 *     // 2. Add to TrackPlayer with the CRITICAL headers
 *     await TrackPlayer.add({
 *       id: videoId,
 *       url: url,
 *       title: details.title,
 *       artist: details.author,
 *       artwork: details.thumbnail,
 *
 *       // --- THE MAGIC PART ---
 *       // You must pass the headers so the player sends them with the request
 *       headers: headers,
 *       // Some versions of TrackPlayer/ExoPlayer need this explicitly:
 *       userAgent: headers['User-Agent'],
 *       // ----------------------
 *     });
 *
 *     await TrackPlayer.play();
 *
 *   } catch (error) {
 *     console.error('Playback failed:', error);
 *   }
 * }
