/* Cartes à accordéon : hauteurs égales sans étirement.

   La grille étire ses cellules à la hauteur de la plus haute. Ouvrir un
   programme allongeait donc la voisine restée fermée, dont le .formation__desc
   (flex-grow: 1) absorbait la différence — un grand vide en plein milieu.
   Ne relâcher l'étirement qu'à l'ouverture réglait le vide, mais faisait
   « retomber » les voisines à leur hauteur réelle : un saut au clic.

   On supprime donc l'étirement en permanence, et on égalise les hauteurs par
   le contenu : la description occupe au moins 4 lignes, ce qui suffit à tous
   les libellés actuels, en français comme en anglais. Les cartes sont alors
   naturellement de même hauteur, et ouvrir l'une ne déplace plus les autres. */
