     la barra inferior se oculta para que el compositor (escribir y hablar) quede libre; la salida es la flecha ←.
   - Cuaderno: cabecera compacta (≈100 px en vez de ≈330 px). Nada queda fuera de pantalla: las herramientas
     se abren en un panel que envuelve, no en un scroll horizontal (commit b0a4dc85).
