-- DEV-ONLY: this environment's real Steam auth against MPAPI's backend fails
-- (confirmed live: "Steam auth failed: Server returned status 502", leaving
-- MPAPI.connection_state permanently "disconnected"/"Offline" -- the exact
-- state visible in every earlier reference screenshot's Multiplayer sidebar
-- too, so this was never actually connected in any prior session either).
-- MPAPI ships its own dev-auth bypass (BalatroMultiplayerAPI/dev/init.lua,
-- stripped from release builds) for exactly this -- authenticates against a
-- temp/ephemeral account via the local server instead of real Steam. Applied
-- here (our own mod) rather than editing MPAPI's shared source directly, and
-- as early as possible (top of core.lua, before any of our own directory
-- loads) since auth fires automatically during boot -- this needs to land
-- before that first attempt, not just before our other code runs.
-- Also respects BMP_IMPERSONATE_ID/BMP_IMPERSONATE_NAME (mirroring MPAPI's own
-- dev/init.lua logic exactly), so a second/third test instance can log in as a
-- distinct real player row instead of every instance colliding on the same
-- ephemeral "DevPlayer" temp identity -- needed for lobby join to make sense
-- across 2+ locally-tested instances.
