Function payload

payload<P extends object>(): PayloadMarker<P>
Phantom payload marker used to declare the payload type for a named variant inside defineMsgs. Returns a no-op token the builder uses to type-thread its variant constructors. The payload object itself is never instantiated at runtime — the helper only forwards the kind plus the user-supplied payload.
Type Parameters
- P extends object
  The payload object type for the variant.
Returns PayloadMarker<P>
Example
```
const msg = defineMsgs({
  set: payload<{ value: number }>(),
  reset: null,
})
```
