+### Recognition Control
+`IRecognitionControl` manages the per-camera image processing lifecycle (start/stop/pause, image loop, events). `BaseRecognitionControl` provides the threading, loop, and event infrastructure — subclasses implement `Initialize`, `WarmUp`, `ProcessImage`, and `GetRecipesData`. Each camera gets its own singleton instance via the child kernel. For full implementation guide, settings reference, and existing implementations, see [`docs/RECOGNITION_CONTROL.md`](docs/RECOGNITION_CONTROL.md).

 ### DI Container
 Ninject `StandardKernel` is the root container. Child kernels (`Ninject.Extensions.ChildKernel`) scope per-camera services. All service resolution flows through the kernel — avoid `new` for services.

 ## Conventions
 
-- Target platform is **x64** Windows.
+- Target platform is **x64** Windows, but new code should be cross-platform — use Avalonia for UI, avoid WinForms-only or Windows-specific APIs.
 - Culture is forced to `en-US` at startup.
 - Nullable reference types are enabled across most projects.
 - Operation attributes: `[Category("name")]` for UI grouping, `[NotForTool]` to exclude properties from serialization, `[IgnoreOperation]` to hide from discovery.
