/* =============================================================================
   Acacia Center for Justice — Timeline styles
   All rules are scoped under .acj-timeline to avoid affecting the rest of
   the site. Loads only on Timeline page/single/shortcode (see inc/enqueue.php).

   Design tokens intentionally mirror acj-reda/assets/reda.css and
   acj-blog/assets/css/acj-blog.css (same brand green/orange, same Besley +
   Public Sans, same spacing/radius scale). Tokens live on .acj-timeline,
   not on :root.

   Visual thesis: a forest-green spine through warm paper; orange ticks like
   warning lights; Besley dates as the loudest type on the track; Public Sans
   for the record. Horizontal on a desk, a vertical ledger on a phone.
