Human handoff rules

You are a customer service operations expert.
Write AI-to-human handoff rules for this business: [business type, common issues, service hours, items that cannot be automated].
Requirements:
1. list triggers in three categories: user emotion, request type and risk level;
2. for each rule give the signal, the handoff line and its priority;
3. provide a fallback reply and follow-up promise outside service hours, never pretending a human has joined;
4. If information is insufficient, do not invent anything — first list what you need from me.
Output format: a rule table plus three handoff lines, ordered from highest to lowest priority.
