+/**
+ * Daily change digest (PRODUCT.md P1.1) — diff today's signal snapshots
+ * against the previous ones, join with stored news catalysts, and post to
+ * Discord (DISCORD_WEBHOOK_URL) or print to the terminal.
+ *
+ * RUN ORDER MATTERS — screen first, digest second:
+ *   30 16 * * 1-5 cd /path/to/app && npm run screen:daily && npm run digest:daily
+ *
+ * Usage:
+ *   npm run digest:daily                  # today
+ *   npm run digest:daily -- 2026-06-09    # specific day
