/* ---------- Facts ---------- */
/* Grille 3 colonnes EGALES, et non plus un flex-wrap : en flex, chaque pavé
   prenait la largeur de son texte — trois pavés de tailles différentes, dont un
   très large depuis l'ajout de Lyon. En `repeat(3, 1fr)` ils font tous la même
   largeur, et `align-items: stretch` (défaut de la grille) leur donne tous la
   hauteur du plus haut : le texte peut passer sur deux lignes sans casser
   l'alignement.
   Pas de max-width, contrairement à `.rooms` (920px) : les colonnes prennent
   toute la largeur de section, comme `.gallery`. C'est délibéré — un des trois
   pavés porte une phrase entière (les distances), et à 920px elle tombait sur
   trois lignes au lieu de deux. */
