Session ID
Where to find it
Your license is linked to the Stripe Session ID created when you completed checkout.
If you saved the recovery page URL from your purchase, it already
contains the Session ID as ?session_id=....
You can also keep a copy of the downloaded license.json,
this recovery page, or the Session ID itself for future access.
