This static book reader does not load analytics by default.
The build script only injects Google Analytics when GOOGLE_ANALYTICS_ID is set in the environment. If analytics is enabled for a public deployment, the deployment should add the appropriate consent and disclosure flow for the jurisdictions where the site is available.
The book chat, when enabled, sends the user's question and recent chat context to the configured OpenAI API endpoint so it can answer from the indexed canonical chapter draft. It should not be enabled without a clear disclosure on the published site.
