[Tuesday, Jun 16] - Analog Brightness + PCB Finalized

Firmware is DONE! Got trimpot brightness control working - turn the knob, watch the LED respond beautifully.

Hardware: Rerouted the whole back to fit the trimpot voltage divider properly, added a power switch to toggle it on/off (goodbye battery drain anxiety!). PCB is ready to manufacture!

After many firmware bugs, all three pieces are finally working together: smooth fading firmware + trimpot brightness control + clean power management.

Next: Export Gerbers and ship this to JLCPCB!
