/*
 * PS5 Vulkan Template - the UI module: the kit's system calls, on platform.h.
 *
 * The kit logs, reads the clock and sleeps through five functions of its own
 * (platform/ps5/system.hpp in PS5_VKHomebrewUI). Here they are the title's
 * klog and clock. The title already dismissed the splash, and it ends by
 * returning from its render loop, so park and quit are never the way out;
 * they keep the kit's contract all the same.
