+# over Vulkan, sharing textures with Minecraft's OpenGL context via Win32
+# external memory + semaphores.
+#
+# Phase 0 scope: bring up a Vulkan device and PROVE the interop capabilities we
+# need actually exist on this machine. No NVIDIA headers required yet -- the
+# Streamline/NGX integration is added in phase 2 (see STREAMLINE_SDK_DIR below).
