Module target 

Export targets as data (ADR-0008 §1): a TargetProfile says what a target’s display shows, how fast it runs, what the player can press, what a game may spend there, and which platform backend builds it. The engine’s profiles are the files of targets/ at the repository’s root (playdate.ron, steam-deck.ron, …); a game adds one, or overrides one by its id, with a file of its own. As a format (ADR-0007): TargetRon.

Every unit is an integer: pixels are u16, milliseconds u32, bytes and instructions u64.
