  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)
