// Each entry tweaks the physical levers in calcVehicleInteriorTemp:
// albedo - how much solar the bodywork reflects (0 = black, 1 = mirror)
// glazingArea - relative sun-exposed glass area (1.0 = typical car)
// glazingArea - relative VERTICAL glass area (1.0 = typical car). A coachbuilt
// motorhome has a huge near-vertical windscreen plus cab side
// windows, so it is far from the 0.25 once assumed here.
// roofGlazing - relative HORIZONTAL glass area (rooflights / Heki hatches /
// panoramic glass roof). Gains from these peak at high sun,
// which is exactly when the vertical-glass term is tailing off.
// bodyU - effective body/panel conductance into the cabin. Cars are
// thin metal/glass boxes; motorhomes/caravans have insulated
// sandwich panels, commonly around 25-35 mm thick.
// hCabinLoss - effective heat rejection/infiltration from the cabin air.
// thermalMass - lower values mean the interior warms more slowly in the hour.
// Motorhomes/caravans reject heat more SLOWLY than cars (better
// sealed, smaller aperture per unit volume), which is why a
// closed-up van gets as hot as a car despite its insulation.
// ventMult - how much opening the windows multiplies hCabinLoss when
// parked. A car with all windows down flushes far more
// effectively per unit volume than a van with two windows and
// a rooflight open, so this is not a shared constant.
// lagHours - interior thermal time constant. This is a DELAY on reaching
// the hour's equilibrium, not a reduction of it - see the note
// in calcVehicleInteriorTempPass.
// retainedWarmth - occupied insulated living spaces hold heat from previous
// hours, people, appliances, and background heating.
// internalGain - small living-space warmth boost when closed up.
