Reference creatortrack prod service scope

creatortrack-prod.service (port :3070, app.creatortrack.ai) is a system systemd unit under /etc/systemd/system/, not a --user unit. Redeploys require:

cd /home/justinwieb/creatortrack
npm run build && sudo systemctl restart creatortrack-prod.service

systemctl --user restart will fail/no-op since the unit isn't in the user scope. This tripped up a session that assumed user-scope by default (consistent with other CreatorTrack dev-slot services).

Why: discovered live during a favicon deploy when --user restart didn't find the service; had to locate it and re-run with sudo.

How to apply: any future prod deploy/restart script for CreatorTrack must use sudo systemctl restart creatortrack-prod.service, not --user.
