Section titled “Returns”core-sys.ts
Engine infrastructure surface: platform, lifecycle, logging, diagnostics, timers, entity helpers, networking, screen.
These are the “runs under everything else” primitives that a consuming application might touch (logging, timers, platform detection, runtime config) but that are not directly part of the ECS or render pipeline.
