⚠️ DEMO: sign-in issues an XSTS-shaped token signed
with a locally generated test key (not Microsoft), saves are stored
in this container instead of S3, and “pre-signed URLs” are local HMAC
tokens. Demo data only — nothing here talks to Microsoft or AWS.
Sign in
Production sign-in happens in the Xbox client via Microsoft/XSTS.
In this demo, enter any gamertag to receive a demo token.

Upload a save
Upload uses the production flow: request an upload URL from the
API, then send the file bytes straight to that URL (S3 in production).
