/**
 * RG Library Grid
 *
 * Every selector is scoped under #rg-lib and every class is prefixed rg-lib-,
 * so your existing page CSS for .caln / .rg-ic / .rg-tip / .featured_image /
 * .acf-book-author / .one-fourths cannot reach these cards. That old CSS was
 * overriding the grid with !important, which is what pushed the access badge
 * onto the cover corner and broke the tooltips.
 *
 * Turn on "Also emit legacy class names" in the settings if you need the old
 * names back for a third-party script.
