    "30 top commuter towns routed to their NYC terminal in ONE multi-source kernel pass at 08:00 peak; rail cheaper 30/30, faster 26/30.",
    "Avg one-way: RAIL $16.91 vs DRIVE $58.23 -> ~$1,818/month saved (drive incl. $9 CRZ + $35 parking + tolls).",
    "Fares are REAL: reso_etl zone tariffs (NJT/LIRR/MNR peak), Edison->NY $13.75 validated; MNR New Haven line extrapolated beyond the DB's zone-11 ladder.",
    "Drive cost real (EIA gas / EPA MPG); drive TIME is OSRM free-flow x1.9 peak (interim \u2014 Valhalla isn't deployed, no traffic table).",
    "Remaining crow-fly (egress walk/bike) is the Phase-E4 graph job; tolls/ride-hail/parking are estimates pending Q2-2026 DB layers."
