# zephyrus-media play-pause | next | previous — the media keys, through MPRIS (playerctl), with a short
# notification of what happened. Shipped by the mesh's asus-zephyrus-g14 module; edit the catalogue.
#
# From the predecessor's media-control, kept: the lock against a double fire (the vendor keys can
# repeat), and the notification. Dropped: its fallback to a media server's local API, which needed a
# token from a file of secrets (novox/hq research 027 question 2). A player that speaks MPRIS is
# reached; one that does not says so.
