/* Cards are uniformly sized — photo (when there is one) and name. Legacy switched
   between three layouts on the two back-office image flags, which made one grid look

   has the name drawn into it (titreInclusImage) hides it rather than printing the name
   twice. See cardFor() in the page module. */
