/**
 * Temporary discovery script.
 * Goal: Inspect the shape of notes returned by the ServiceChannel API
 *       to determine the correct timestamp field name.
 *
 * Run with: node discover-note-timestamps.js
 *
 * This script now loads credentials from environment variables (via .env)
 * — same as the main app — so there's no plaintext credential in this file.
 * Feel free to delete once you're done using it.
