# Flathub remote + the two apps this image needs that Debian does not package:
# the official Spotify client and Prism Launcher.
#
# Same distribution channel and the same "don't pin a version that will just rot"
# reasoning as hosts/touch-panel's 0300-flatpak-spotify.hook.chroot and
# hosts/thin-client's 0400-flatpak-steamlink.hook.chroot.
#
# Note what is NOT here: Steam. Steam is installed natively from apt by
# 0300-steam.hook.chroot, deliberately — the Flatpak runs sandboxed with its own
# runtime, which complicates GPU driver matching, controller udev access and mounting
# a games disk, all of which matter on a machine whose whole job is running games
# locally. Prism and Spotify have none of those constraints, so the sandbox is a
# straightforward win for them.
