V10a: Multiple player accounts on one device

The latest Erleuchtung release, V10a, lets players request and use multiple accounts on the same approved device.

This is important for families or communities that share one computer or tablet — for example, in many regions of Africa. It is also useful for testing Ledger support with several players on the same Mac, alongside Trezor. All other devices keep the standard one-account-per-device protection.
