## Ejemplo

```ts
import { pw_keyboard_sequence } from "./pw_keyboard_sequence";

await pw_keyboard_sequence(page, [
  { kind: "focus", selector: "input[name=requester]" },
  { kind: "type", text: "Enma" },
  { kind: "wait", ms: 200 },
  { kind: "press", key: "ArrowDown" },
  { kind: "press", key: "ArrowDown" },
  { kind: "press", key: "Enter" },
]);
```

## Cuando usarla

Cuando necesites encadenar foco + escritura + teclas especiales sobre un elemento (autocompletado, selects, modales de búsqueda). Úsala en tests E2E con Playwright en lugar de mezclar calls sueltas de `keyboard.type` y `keyboard.press`.

## Gotchas

- `focus` usa `.first()` — si el selector coincide con múltiples elementos, foca el primero. Afinar el selector si es necesario.
- `type` simula escritura carácter a carácter con `delay` (default 30 ms). Para input más rápido pasar `delayMs: 0`.
- `press` espera un nombre de tecla Playwright válido: `"ArrowDown"`, `"Enter"`, `"Escape"`, `"Tab"`, etc.
- Un `kind` desconocido lanza en runtime (útil para detectar typos en JS sin TypeScript).
