+/**
+ * #1485 — Live map: animated packets render BEHIND the node base layer.
+ *
+ * Regression introduced by PR #1334 (commit 0f7c03cc), which swapped node
+ * markers from L.circleMarker (lives in `overlayPane`, z=400) to L.marker
+ * with divIcons (lives in `markerPane`, z=600). Animations stayed in the
+ * default overlayPane (z=400 — polylines + circleMarkers) so once node
+ * markers populated the map, they painted ON TOP of the animation layer,
+ * hiding moving packets entirely.
+ *
+ * Fix invariant: the animation layers (animLayer + pathsLayer) must be
+ * created on a CUSTOM Leaflet pane whose z-index is strictly greater than
+ * the default markerPane (600). The conventional CoreScope choice is a
+ * pane named `liveAnimPane` at z=650 (tooltipPane sits at 650 too, but
+ * tooltips are user-triggered and harmless to share).
+ *
+ * Strategy: source-invariant assertions on public/live.js. We pin:
+ *   1. A custom pane is created via map.createPane('liveAnimPane', ...).
+ *   2. Its z-index >= 650 (covers markerPane @ 600).
+ *   3. Both animLayer and pathsLayer are constructed with `pane:`
+ *      pointing at that custom pane (so polylines + circleMarkers inherit
+ *      the pane, not the default overlayPane).
+ *
+ * Behavioural check via vm sandbox: simulate the layer-creation calls
+ * and assert addTo()/L.layerGroup() receive the pane option.
