Debug overlays are development aids drawn on top of the regular page + * content. They never participate in measurement or pagination, so enabling + * them does not change the layout graph — and leaving them disabled (the + * default) keeps rendered documents byte-identical to previous releases.

+ * + *

Two overlays are available:

+ *
    + *
  • Guides — fragment boxes plus dashed margin/padding rectangles, + * the overlay previously toggled by the {@code guideLines(boolean)} + * convenience switch.
    • + *
  • Node labels — the stable semantic path of the owning node + * printed once per node and page at the top-left corner of the node's + * bounds. Labels make a misplaced block traceable back to the exact + * builder call that authored it: name nodes via the DSL (for example + * {@code pageFlow().name("InvoiceSheet")}; module titles auto-name + * their blocks) and the same name appears on the sheet and in + * {@code DocumentSession.layoutSnapshot()}.
    • + *
+ * + *

Typical usage through the session convenience API:

+ * 
{@code
+ * try (DocumentSession document = GraphCompose.document(out)
+ *         .debug(PdfDebugOptions.guidesAndNodeLabels())
