# input_manager.ludic — the Input Manager (#83): default bindings a game ships and
# a player rebinds, and device-agnostic actions that read the multi-key device
# layer across keyboard and gamepad, with clean on-press / on-release edges. Driven
# headless by injection (Input.press / Input.set_pad), the same way #7/#50 test.
#
# Deterministic; a full run prints:  1 1 1 0 1 0 0 1

    # (The just_pressed/just_released *edges* also work across the pad in a real
    # windowed game, where the platform refreshes the pad each frame; the headless
    # injection path here exercises the device-agnostic `active` read.)
