+ * to load entirely, preventing the webmention sender from starting.
+ *
+ * Root cause: typo in the upstream package — an extra `"` after the string
+ * literal `"h-entry"` makes the JS parser see an unterminated expression:
+ *
+ *   _html.includes("h-entry"")   ← broken
+ *   _html.includes("h-entry")    ← fixed
