+// The packer marks a child as "static" (skip-repack) only if

+// to staticPcbComponentIds when the nearest subcircuit resolves a
+// manual placement for it.
+//
+// Mirrors the failing case in loco-boardv2: a chip inside an anchored
+// region with several auto-placed bottom-side caps. Without the fix the
+// inner packer dumps every cap on top of the chip's network-minimum
+// point; with manualEdits and the fix, the caps land at the requested
