 Note that layout registrations do not persist across domain reloads. Instead, the Input System relies on all registrations to become available as part of the initialization process (for example, by using `[InitializeOnLoad]` to run registration as part of the domain startup code in the Editor). This allows you to change registrations and layouts in script, and the change to immediately take effect after a domain reload.
