     26  * The base layer (0) provides standard numpad functionality with:
     27  * - Numbers 0-9 in traditional numpad layout
     28  * - Mute button in top right
     29  * - Layer 1 momentary toggle (MO1) in middle right
     30  *
     31  * The function layer (1) adds:
     32  * - Basic mathematical operators (+, -, *, /)
     33  * - Backspace, Enter, and decimal point
     34  * - Equal sign for calculations
     35  * - Empty slots marked as ---- (KC_NO)
