## [kbd]E[/kbd] → [code]prototype_terminal[/code]; [kbd]R[/kbd] → [code]prototype_resource_node_alpha[/code]
## (stable contract ids — must match server registry). Key handling is delegated from
## [code]main.gd[/code] [method Node._unhandled_key_input] (see [method post_interact_terminal] /
## [method post_interact_resource]) so the embedded Game dock still receives E/R reliably.
