+/**
+ * Structural regression guard for #146 (PR #147).
+ *
+ * The caret/click-offset fix rests entirely on ONE invariant: in every editable
+ * footnote NodeView the editable `NodeViewContent` (contentDOM) must be the
+ * FIRST child of the wrapper, with no non-editable (`contenteditable="false"`)
+ * element before it. If a future edit reinserts chrome (separator, heading,
+ * marker, back-link) ahead of the content, the macOS hit-testing bug returns
+ * silently — and the symptom needs a real browser to see. This test pins the
+ * DOM ORDER (the proxy that IS the fix) in the existing jsdom harness.
+ *
+ * We stub `@tiptap/react` so the views render as plain DOM and we can inspect
+ * the child order our JSX produces — that order is exactly what regresses, and
+ * it does not depend on a live editor. The stubbed `NodeViewContent` carries the
+ * real `data-node-view-content` marker tiptap uses, so the assertion mirrors
+ * production. This test passes on the fixed order and FAILS on the pre-fix order
+ * (chrome-before-content).
