Everyone starts as a listener. An admin can upgrade you to artist, partner, or admin.
Listener: favorite / skip / comment · Artist: own catalog · Partner: imprint tools · Admin: everything + upgrades.
New people are listeners. Upgrade: listener → artist → partner → admin. Bind a roster pin and imprint when they become artist or partner.
Templates + any links saved from this browser. Re-upload partner-accounts.json with the full site zip to persist for everyone.
