# media module -- MPRIS media controls via playerctl (works with most
# players automatically: Spotify, VLC, mpv, Firefox/Chromium tabs, etc.),
# dispatched by subcommand. Controls whichever player playerctl considers
# active (usually whichever was most recently active) -- run `playerctl -l`
# yourself to see all available players if you run more than one at once.
#   media.sh            -> bar text: play/pause glyph + "Artist - Title"
#   media.sh track      -> "Artist - Title", undecorated (popup info row)
#   media.sh art        -> path to a local album-art image file, or nothing
#                          if the current track has none (popup image row;
#                          downloads+caches remote art URLs via curl)
