/*
  Freedom (Omeka S) – Item Sets Grid Override
  ------------------------------------------------
  What this does:
  - Forces the Item Sets browse page (/item-set) into a responsive card grid.
  - Keeps the rest of the site untouched.

  How to use (choose one):
  A) CSS Editor module: paste the contents of this file.
  B) Theme file: save as /themes/freedom/asset/css/item-sets-grid.css and enqueue it.

  Notes:
  - Selectors are intentionally redundant to accommodate slightly different body-class conventions.
  - If your install uses a different wrapper than .resource-list/.resource, inspect the page and
    adjust the selectors accordingly.
