Description

Two or more headings in the same document resolve to identical text (ignoring case and whitespace).

Duplicate headings create ambiguous slug anchors (e.g. #section vs #section-1), breaking deep links and confusing document outline navigation.

---

How to Fix

Rename headings so that every section has a unique, descriptive title.

---

Suppression

If duplicate headings are required by design, suppress the warning with an inline comment:

<!-- zenzic:ignore:Z513 -->
