feat(short): el ejemplo del prompt habla, y por eso los specs vuelven a hablar

La primera generación con narración viva narró 5 de 7 planos. La siguiente, ya
con la sección de presupuestos de ancho en el prompt, narró 1 de 8.

La causa no era la sección 3b sino la 5: el ejemplo trabajado — un spec completo
de 8 planos presentado como "el que produjo un buen vídeo" — no llevaba ni una
narración, porque es anterior a la voz. Contra esa señal de formato, una regla
en prosa que además dice "no todos los planos necesitan una" pierde siempre.

Ahora el ejemplo narra 6 de sus 8 y calla en los dos que dibujan una cita, donde
la voz sólo competiría con palabras que ya están en pantalla. Sus duraciones
suben para pagar lo que habla: un plano que se queda corto para su propia voz
enseñaría a infradeclarar, y el render no corta la voz, alarga el plano. La
ventana de silencio se recoloca porque seguía a document_quote por tiempo.

El aviso de ancho ya no cita el hueco de 16 caracteres de quote_a: shortsmith
envuelve esas citas en dos líneas y el presupuesto vivo es 31.
