Same 36 keys, columns offset for finger length, spacebar broken into four
stepped thumb keys. Comes out ~7u wide instead of 8.5u because the function
row loses the 104's arbitrary gaps.
Also records the tenting dependency: hardware is CAD, but mounting holes are
PCB and need a case scheme chosen before routing.
