Accident Scoreboard w/ Old-School Bulb Display

You asked for it! After nailing my finger to a sign frame, I took your advice and created an old-fashioned workplace "accident scoreboard," but with an auto-incrementing readout, fashioned after the now-obsolete, but much more aesthetically pleasing, incandescent "eggcrate" displays of old.

CIRCUIT INFORMATION
I'm using an Adafruit ItsyBitsy 32u4 (5v) to run the display, with an Adafruit PCF8523 real time clock breakout board to read the time. (Both linked above.) I'm using three 74HC595N shift registers to trigger the 22 channels in the display, each switched using an FQP30N06L logic-level MOSFET. The bulbs are all 12VDC #428 miniature-base (E10) incandescents. The buzzer and the button are both listed above.
