// Unity to LogRocket iOS bridge.
//
// Uses __has_include so this file compiles whether or not the LogRocket pod is
// integrated. When the pod is present the real, type-checked SDK calls compile
// in; when absent every entry point degrades to a no-op so non-LogRocket builds
// still link.
//
// To enable: add `pod 'LogRocket'` to the generated Podfile (or an EDM4U
// *Dependencies.xml), run pod install, rebuild. API verified against the
// LogRocket iOS SDK 3.x Objective-C surface (docs.logrocket.com/reference/ios):
//   LROSDK, LROConfiguration, LROCustomEventBuilder.
//
// NOTE: the LogRocket SDK is a Swift framework; its objects are ARC-managed.
// Compile this file with ARC (-fobjc-arc). Unity's generated project enables
// ARC by default; if you see leaks, confirm the flag on this file.
