Detailed Description

The igniter port through the centre of the injector plate.

Hardware, not a requirement: the thread is what was bought, and every keep-out follows from
it (engine/core/injectors/hardware_tables.NPT). Declaring this derives the centre keep-out
that ``layer1_injector_center_clear_dia_m`` used to be typed in as a bare number (1.5 in on
the shipped designs, against the ~25 mm a 1/2 NPT port needs); an explicit value for that
key still wins and the layout reports both.
