//! Integration coverage for client input-device classification helpers.
//!
//! Scope: include the input aggregator source and exercise private device
//! classification against synthetic uinput keyboard/mouse devices.
//! Targets: `client/src/input/inputs.rs`.
//! Why: device classification regressions can silently break all input capture
//! at runtime, so classifier behavior should stay under contract.
