# Appends absolute paths to $SLAB_HOME/state/open-video; the menubar's 2 s
# tick consumes the file and raises a chromeless AVKit panel per movie
# (plays immediately; Esc closes, space toggles, one "QuickTime" button
# escapes to QuickTime Player). Re-asking for an open file brings its
# window forward and restarts playback. The panel watches the file and
# reloads on rewrite, so render loops feel live. See
# slab/menubar-swift/Sources/SlabMenubar/VideoViewer.swift.
