"""
The JLCPCB footprint for the Kailh hotswap sockets is centered around the socket alone.
Unlike the the Acheron MX100H footprint that I am using for the entire switch (holes and socket).
Hence, some fiddling is required to position the socket in the right place - which can be confirmed
in the JLCPCB assembly viewer.
