Treat every Input System package workflow/API claim below (Action Maps, PlayerInput, control schemes, device pairing) as **pretrained knowledge, explicitly flagged as such** — verify precision against the in-Editor Package Manager docs (Window > Package Manager > Input System > View Documentation) or the package's own `Documentation~` folder/Samples before shipping code from this skill unmodified.
