CHAPTER 12 and CHAPTER 19 — Rule-based FAQ helper

Open index.html locally in a browser. No network requests or remote AI calls. faq_logic.js contains example questions and fixed responses approved ONLY for the fictional case study.

Four states: known answer, clarification required, unknown answer, human handover. Unknown or high-risk questions must not trigger invented facts. Review test_cases.txt.

IMPORTANT: Do not publish this demonstration as a real business support service. Replace fictional content, check accessibility, security, owner approvals and actual verified contact routes first.
