+{# Override of pydata_sphinx_theme's components/navbar-nav.html.
+
+   PyData's default renders both top-level toctree items AND the configured
+   external_links in one bar. For OpenCV we want ONLY this header nav (the
+   tutorial module tree belongs in the left sidebar, not the header), so we
+   render the `external_links` slot exclusively.
+
+   These are NOT external links: conf.py declares them via the theme's
+   `external_links` key only because that's the data slot for a custom header
+   nav. Each entry is one of:
+     * internal  -> {"docname": "<docname>", "name": ...}
+       resolved with `pathto` so the relative URL is correct at ANY page depth
+       and points at the Sphinx-rendered page (landing, tutorials, module roots);
+     * external  -> {"url": "<abs-url>", "name": ..., "external": true}
+       rendered verbatim and opened in a new tab (e.g. the Java docs, which
+       have no Sphinx equivalent).
+
+   Internal entries carry no target="_blank" / nav-external glyph since
+   navigation never leaves the site. #}
