+// pre-resolved node ids and may freely cross cluster borders.
+//
+// Color contract: classes/edges marked for removal stay red; packages that
+// need to be broken up render pink — clusters via `style=filled fillcolor=pink`
+// when the package has no node of its own, package-map rectangle nodes via
+// `color=pink style=filled` (a pink node inside its own pink box would hide
+// the signal). Every cluster declares an explicit fill (white when unflagged)
+// because vizdom propagates a styled cluster's fill to its nested cluster
+// rects — the explicit white keeps child packages of a pink cluster on their
+// normal fill; white is vizdom's default cluster fill, so nothing changes
+// visually for unflagged clusters. Label colors: shapes default to white
+// fills (probe: cluster rects render fill="white" stroke="black"), so node
+// labels stay readable on every palette without synthesis-time color.
+// Non-hovered node labels keep the baked black ink; hovered or focused
+// node labels re-ink to the CSS --graph-hover-on; regular and break-up
+// cluster labels are recolored by CSS along with their rects
+// (--graph-line / --graph-breakup-line). Only edge labels sit on the page
