/* ============================================================
   AIN Topology Graph — additions for the revamped Live Map
   - Custom hover tooltip (nodes + edges)
   - Side-panel header icon
   - Connection rows with port info
   These complement (not replace) the existing .topo-* rules in
   styles.css.
