Switcher Name settings section — set the ATEM's OWN stored name (the name set in
ATEM Setup), via the ATEM's REST config API (control/device_api.py + the
atem_device_info / atem_set_device_name views). A host that knows this address by
another name (its own inventory; here, what mDNS advertises) offers it as
"use <name>" — never in a host's vocabulary, this package has no inventory.
Minimal by design (matches the other settings sections); self-contained inline
Alpine (no bundle rebuild); loads on first open. openSections.switcherName is the
outer scope.
