   ARADEL NEWS CARDS & ARCHIVE
   File: /wp-content/mu-plugins/aradel-news.css

   IMPORTANT: Uses .ar-card--news only.
   Does NOT touch .ar-card--media (existing overlay cards).

   CHANGELOG v1.3
     - Card ease-in animation: @keyframes ar-card-in, applied via JS stagger.
     - .ar-news-filter-group-label: non-clickable dropdown section headers.
     - .ar-news-filter-reset: Reset Filters text button style.
   CHANGELOG v1.2
     - .ar-news-tabs/.ar-news-tab restyled to match .ar-segmented
       pattern from timeline: full-width track, #F0F3F4 bg,
       #01303A filled active pill, white text.
     - .ar-news-filter-btn/dropdown/option restyled to match
       Reg Announcements pill + dropdown pattern.
     - .ar-news-filter-submit restyled to match .ar-reg-page__submit.
     - .ar-news-loadmore-wrap/.ar-news-loadmore restyled to match
       .ar-reg-page__load-more-wrap pattern.
