CI / build-test (push) Successful in 1m24s
Core now depends only on Friflo.Engine.ECS — no MonoGame, no platform. The windowed MonoGame host moves to the new MrGameEng.Host library: GameHost, GameHostOptions, visual scene transitions (OverlayTransition, Transitions.Fade/Wipe, TransitionRenderer) and the Input feature (namespace MrGameEng.Input is unchanged). Transition timing stays in Core (SceneManager exposes ActiveTransition/TransitionCoverage/ TransitionPhase; the host draws the overlay). EngineContext loses its GraphicsDevice property: hosts publish the device as a service and graphics code reads it via context.GetGraphicsDevice() in Graphics. Core gains HeadlessHost: a fixed-timestep loop without a window or GPU (Tick/RunTicks, Run with wall-clock pacing and lag resync) for dedicated servers, batch simulation and tests. Graphics and Audio now carry their own MonoGame.Framework.DesktopGL reference instead of inheriting it from Core. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
