Open playable 3D root (new tab)

This manual page stays open; its checkpoints remain page-only.

Reloading or closing ends both manual sessions. Explicit exports are diagnostic copies only, not score submissions.

Not the playable 3D release. No official course association, native Actual connection, or hub sync.
