★ 4×3 switch matrix with 10 populated positions

★ Through-hole diodes for the switch matrix

Coding Mode is designed for VS Code and includes:

The bottom-center key switches between Coding Mode and Daily Mode.

The OLED displays the current mode, and the RGB LED changes color to indicate the active mode.
