+-- Hammerspoon: draw a ring around the Mac pointer so it shows in the VNC
+-- mirror on the Frame. macOS Screen Sharing leaves the pointer out of the
+-- framebuffer; a real on-screen window is captured like anything else.

+-- Install: brew install --cask hammerspoon, then in ~/.hammerspoon/init.lua:
+--   dofile("/path/to/frame-control/scripts/mac-cursor-ring.lua")
+-- Toggle: ctrl+alt+cmd+M. Polls the pointer position, so no Accessibility
