SteamVR debugger and Docker keep only the internals the docs lack; the screenshots script names package.nix as what prepends its variables.

# dashboard on 127.0.0.1:8087, on (mkDefault) when a patch targets port 8087.

# The steamvr-webhelper-debugger oneshot runs `install.sh steamvr-debugger-arm`
|
|
# before each SteamVR start, through a Wants/After drop-in on steamvr.service
|
|
# (ExecStartPre= would be too late: vrserver starts in the unit's own chain).
|
|
# The arm step reloads systemd only when its runtime drop-in is new (once per
|
|
# boot). Off: no unit and no drop-in; cleanup restores the key.

dashboard patches, which turn it on automatically. Set only while
