Catch placeholders before buyers see them.

No API key, bearer token, or password is stored in node parameters. Credential-dependent nodes have generic credential names. Example domains are marked as examples or replaced with real setup variables. Required environment variables are listed in one place. Slack, Airtable, Google, CRM, and email accounts are described as buyer-owned. Webhook paths do not include private customer or project names. Test payloads are generic and safe to share. The buyer can identify what to change before first run.
