"""Studio: orchestration shell for animation development.

The Studio class is a thin convenience facade. It holds no direct reference to
model code; every pixel mutation routes through pixel_cursor.PixelCursor.write_*.
Enable a backend by importing its adapter (e.g. studio.backends.motionclone) —
the adapter self-registers with pixel_cursor.ops.register_backend.
