+// ── FUTURE FEATURE: Vehicle-at-speed thermal model ────────────────────────────
+// Idea: extend calcVehicleInteriorTemp (or add a companion function) to model
+// cabin temperature for a vehicle travelling at speed, not just parked.
+//
+// Key physics differences from the static model:
+//   • Forced convection over the shell scales with vehicle speed (v²), so
+//     hOut rises significantly — shell cools much faster than when parked.
+//   • Above ~30 mph the vehicle's own forward motion dominates airflow, so
+//     ambient wind direction becomes largely irrelevant (simplifies the model).
+//   • Speed classes to model: urban (~20 mph), dual carriageway (~50 mph),
+//     motorway (~70 mph) — each with a derived hOut multiplier.
+//   • Windows-open behaviour changes completely at speed: at 70 mph open
+//     windows create high-velocity through-flow, dramatically cutting cabin
+//     temp vs. the sealed-car case (but much less pleasant than AC!).
+//   • Roof and bonnet solar gain stays the same; side-glass gain is unchanged.
+//   • AC-off vs AC-on would be the primary user toggle alongside speed class.
+//
+// Suggested signature:
+//   calcVehicleInteriorTempAtSpeed(Ta, globalRad, solElev, vehicleType, speedMph, windowsOpen)
+//
+// This would be a useful companion output column (e.g. "Vehicle (moving)")
+// for road-trip planning, dog-in-car safety at a rest stop vs. motorway, etc.
