🎯 Learning Outcome: Compare feeder link switchover impact across architectures.
🟢 Regenerative (Arch 3): Switchover invisible to UE (U-plane delay only)
🔴 Transparent (Arch 1): Requires full inter-gNB handover
🟡 Make-Before-Break: No service interruption
🔴 Break-Before-Make: Service interruption occurs
