   Mixamo page downloader — paste into YOUR OWN Chrome console.
   (Downloads only persist in a normal browser tab, not automation.)

   SETUP:
   1. chrome://settings/downloads -> turn OFF "Ask where to save
      each file before downloading" (else 10 Save-As prompts).
   2. Go to:  https://www.mixamo.com/#/?page=52&type=Motion%2CMotionPack
      Wait for the character + grid to finish loading.
   3. Open console: Cmd+Option+J  (Mac).  Paste this whole file, Enter.
   4. First download triggers a "Allow multiple downloads?" bar -> Allow.
   Files land in your Downloads folder named "<Animation Name>.fbx".
