Acordeón de preguntas

Opening another question closes the previous one in the same movement: it is a single index in state, and it is what prevents the accordion that fills up until nothing is readable. Two decisions people lose when copying from memory: the answer is ALWAYS in the DOM, because if it only exists once open a search engine never reads it; and the height animates with a 0fr to 1fr grid row, not with a guessed max-height that clips the long answers.
