The banner sits in a single if-let slot; without an identity key, clearing a tip that was covering a network/offline banner swapped content in place with no transition (instantly vanishing). Keying the banner by its value (.id) makes every change — tip→network or tip→nil — run the shared removal transition, so the tip slides up and fades out when it auto-dismisses or is tapped.
