-- hover-loop.lua — mpv script for the cover-video preview windows.
--
--  • Play ONLY while the mouse cursor is over the window; pause the
--    moment it leaves (saves CPU when you're not looking at a clip).
--  • Ctrl+w closes EVERY preview window at once (plain Cmd/Ctrl+w in
--    mpv only closes the focused one — these are separate processes).
--
-- Wired in by preview.sh via --script=.
