+// The inference-engine libraries ship as their own top-level frameworks (their own binaryTargets),
+// listed in every product that needs the engine, so SPM embeds + code-signs each with the consumer's
+// identity on device. This replaces the previous layout where they were dylibs nested inside
+// LeapSDK.framework/Frameworks (Xcode "Embed & Sign" never re-signs nested dylibs, so device dyld
+// rejected them). See Liquid4All/leap-android-sdk#281.
