"""#48 solo reproduction: drive the COMMS panel's target-designation path.

The one comms action never exercised in any rig.  Target designation (typed
t/y/u/i/o, and the Comm bank buttons 0x30-0x37) performs three RAW writes at
`pilotArray[0] + 0x284` (mechmppr.cpp:1344/:1364/:1420) intending the binary's
`objectiveMech`.  Our compiled layout differs from the binary's, so that write
lands on whatever member really sits at byte 0x284 -- the ctor now prints the
real offsets, and this run hammers the designation keys while capturing frames.

Also toggles the pilot list's SELECT-TARGET highlight, which is the branch that
makes PilotList::DrawMechIcon repaint (filled box / inverted blit).

Kills only the PID it spawns.
