Crossplay Leaderboards

Use Write Crossplay Leaderboard with a shared leaderboard/stat ID and an integer score. Steam writes its leaderboard directly; EOS ingests the matching 32-bit stat, so EOS scores must fit in an int32.

Use Read Crossplay Leaderboard with the first rank and result limit. Results contain the source backend, player handle, display name, rank, and score.

Kit-specific nodes provide around-user and explicit-user reads when one platform's ranking view is required.

See C++ usage and the capability matrix.

Use a unified node first. Use a kit-specific leaderboard node only for that platform's exact option set.
