+// Stand-ins for the handful of symbols the node core expects the GUI to
+// provide, so a headless binary can be linked without ImGui, GLFW or OpenGL.
+//
+// This exists because linking the GUI made the node need libGL at load time
+// even when started with -nogui: the dynamic loader resolves everything before
+// main() runs, so the flag came far too late. On a clean server -- which is
+// where a node most naturally lives -- that is a hard failure with an error
+// message about shared libraries and no hint that the program would otherwise
+// have worked fine.

+// The GUI uses this to mark itself dirty. With no window to repaint there is
+// nothing to do, and the call sites in main.cpp and net.cpp stay unchanged.
