/* EDU-ELN · Electronics Playground — a distinct member of the EDU-* series.
   EDU-SQL evokes a mainframe console; EDU-ELN evokes the REPAIR BENCH: a dark
   anthracite chassis with engraved labels, the phosphor-green oscilloscope
   screen, the amber seven-segment glow of a bench multimeter, and wires whose
   colour IS their voltage. The schematic itself is the instrument. */
