/* Timeline Page Styles
   Restyled 30 Sep 2026 to sit with the rest of the site (the Ship Codex /
   Supply Chain cards): same alternating layout down a centre line, but each
   event is a site card - dark panel, thin border, the date as a small
   highlight-coloured label, glow on hover. Events come from the
   timeline_events table (scripts/site_pages_lib.php); SuperAdmins get
   Edit / Remove on each one and "Add a timeline event" underneath. */
