Enroll feeder	#293	Managed node + API key wizard
Setup copy	#296	MC vs MT bot instructions
Docker v3	#295	Compose defaults
Outbound 2FA (UI)	#303	Claim wizard
API outbound 2FA	meshflow-api#361	WS + verify

Suggested order — feeder onboarding

1. API #362 (or fold into first Enroll MeshCore feeder (managed node + API key) #293 API PR)
2. Enrollment #293 — closes Bug: cannot assign API key to MeshCore managed node (400 node_id is required) #254
3. Managed node setup instructions: MeshCore and Meshtastic parity #296 / Docker examples: STORAGE_API_VERSION=3 default in compose #295

Suggested order — outbound claim

Bot #120 → API #361 → UI #303
