+/**
+ * QUARANTINE (2026-07-17): these specs assert the pre-platform-first UI
+ * (element locators, URLs, and subheader copy that the June IA rebuild
+ * replaced) and have failed on every push since 2026-06-29, drowning the
+ * signal from the healthy specs. Quarantining them keeps the rest of the
+ * suite as a live per-push gate while each file is re-pinned to the
+ * current UI and removed from this list. This is a stopgap, not a fix:
+ * the recovery work is tracked as its own effort, and a spec leaves this
+ * list only by being repaired, never by deletion.
