ok so this is after flood-fill, remember that GND wires (blue) which are within tthe GND flood-fill (grey) *are* part of the GND plane, PADS just continues to highlight their existence (unnecessarily).
so this gives a clear idea of how the current (arbitrarily-created) tapers look like. there are no tapers and no keepout areas on layer 1, because the clearance to... "stuff" is unavoidably within 5-7mil anyway.
