## Layer 0: CARP (Carpalx QGMLWY)

```
`/ESC  Q  G  M  L  W  |  Y  F  U  B  ;    TAB
[NAVI] D  S  T  N  R  |  I  A  E  O  H    '
LSHFT  Z  X  C  V  J  |  K  P  ,  .  /    RSHFT
          CTRL  RET  GUI | SPC  BSPC  ALT
```

**Combos (layers 0+1):**
- Top+home row same col = `1`-`0`, shift+combo = `!` `@` `#` `$` `%` `^` `&` `*` `(` `)`

| Key | Behavior |
|-----|----------|
| `` ` ``/ESC | Tap = grave, hold = ESC |
| `[NAVI]` | Hold opens NAVI layer, release goes back |

## Layer 1: QWRT (QWERTY)

```
`/ESC  Q  W  E  R  T  |  Y  U  I  O  P    TAB
[NAVI] A  S  D  F  G  |  H  J  K  L  ;    '
LSHFT  Z  X  C  V  B  |  N  M  ,  .  /    RSHFT
          CTRL  RET  GUI | SPC  BSPC  ALT
