+# docfx emits two C#-generic patterns whose opening `<` is bare while
+# the closing `>` is markdown-escaped as `\>`. Vue's template compiler
+# then treats the bare `<` as the start tag of an element that never
+# closes (the escaped `\>` is rendered as a literal `>` in HTML, not
+# as an end-tag token), tripping "Element is missing end tag" at
+# vitepress build time. The two patterns are:
+#
+#   1. Heading text after the anchor close, e.g.
+#      `### <a id="…"></a> Collect\(string, List<EnvVarInfo\>\)`.
+#   2. Return / parameter blocks where docfx renders an outer-generic
+#      link followed by an inner-generic link, e.g.
+#      ` [List](url-of-list)<[EnvVarInfo](url-of-envvarinfo)\>`.
+#
+# Both forms feed the parser a `<` followed by either an uppercase
+# letter (heading-text type name) or a `[` (markdown link opener) and
+# never close it with a real `</tag>`. Rewrite both bare opens as
+# `&lt;` HTML entities so the markdown -> HTML pipeline can't re-emit
+# a literal `<` (a backslash-escape would survive markdown but the
+# Vue template parser sees the rendered HTML, where `\<` decodes to
+# `<` again and re-trips the same error). The `<a id="…"></a>` anchor
+# itself is intentionally not touched -- `a` is lowercase, so the
+# `<[A-Z]` alternative misses it, and the `<\[` alternative is
+# unambiguous. Fenced code blocks render via the highlighter, not
+# Vue's template parser, so the bare generics they contain (e.g.
+# `public IReadOnlyList<EnvVarInfo> Collect(...)`) do not need
+# escaping. A small awk pass tracks ```-fence state and skips lines
