/* =================================================================
   entity-image-picker.css — Web-image search picker for the per-entity
   user-image feature. Sibling to entity-image-crop.css: this picker
   shows search-result thumbnails; clicking one downloads the URL to a
   temp file and feeds it to the crop modal.

   Visual idiom mirrors entity-image-crop.css and modals.css — same
   surface tokens, button classes (.settings-btn*), border radii, and
   border-subtle dividers. z-index 6050 sits between coverViewer (6000)
   and the crop modal (6100) so a stacked picker→crop flow renders in
   the right Z order.
