Mouse and controller scope

[Official] The Steam store lists controller support, and official updates have separately addressed controller zoom and the controller settings UI. The version 3.5.3 note announces camera X/Y inversion without documenting separate mouse and controller labels.

If the options are absent, recheck the installed version and restart Steam after the update before trying old configuration-file workarounds.

Avoid outdated workarounds

Version 3.5.3 makes camera inversion an in-game feature. Do not edit configuration files merely to obtain a setting that the current build now exposes.

Advice stating that camera inversion is unavailable applies to older builds and should not be used for version 3.5.3 or later.
