   the load-more button and footer can never overlap mid-load — unlike a
   JS-measured grid whose height lags a frame behind inserted cards. Cards opt
   out of column breaks via `break-inside: avoid` (see post/boosty card CSS). */

   balanced. Heights stay browser-computed, so load-more can't overlap. */
