/* ── Hide DEEP (nested) level-6 headings from the sidebar (Vector) TOC
The doc pages carry repeated h6 sub-entries that clutter the TOC. MediaWiki's
heading instead. We hide ONLY NESTED h6: a TOP-LEVEL section that happens to
be h6 (e.g. Cover / Audit Information) is KEPT, because hiding a numbered
top-level entry leaves a gap in MediaWiki's static TOC numbers (0 -> 3). */
