+> This package does have one current product role: it is the **desktop
+> demonstration recorder** behind `openadapt-flow record --backend windows|rdp`,
+> installed via the optional `capture` extra
+> (`pip install 'openadapt-flow[capture]'`). The operator's native
+> mouse/keyboard/screen capture session is converted into the compiler's
+> recording format by `openadapt_flow.adapters.capture.convert_capture` (see
+> openadapt-flow's `docs/desktop/RECORDING.md`). The web recording path does not
+> use this package. Requires `openadapt-capture >= 0.5.3` for headless-safe
+> import.
