# R1.7 (CEC driver cache): Valve's CEC driver is downloaded once and kept in /var/cache/steamify, named after
# its checksum; a new pin downloads its own file and removes the old one, a damaged file is replaced.
# Offline: a private cache folder, and the host's cached copy as the "download" (file://), so GitHub's rate
# limit can't fail this block. Needs the host cache (vmsuite.sh binds ~/vms/pkg-cache/steamify).
