 * Calculates the Time to First Byte (TTFB) for the given window object.

 * This function attempts to use the Navigation Timing Level 2 API first, and falls back to

7
 * @param {Window} win - The window object from which to retrieve performance timing information.
8
 * @returns {string} The TTFB in milliseconds as a string, or an empty string if the TTFB cannot be determined.
