"""The Arena's rendering layer.

Importing this package puts the vendored `bit-ui` on the path, so every module
under it can `from bit_ui import ...` without repeating the dance. bit-ui
travels as a git submodule and is uploaded to the Space as ordinary files, so
there is nothing to install at boot.
