++ # R58 (skill-language-style): a module landing page must include a
++ # Reference section (with links to C++ Classes/QML Types). Same proven
++ # pattern as ModuleExamplesSection.yml / PageOverview.yml.
++ # APPLICABILITY: this is a whole-file presence check, scoped in
++ # .vale-qdoc.ini to a [*-index.qdoc] section, not the general [*.{qdoc,...}]
++ # section, so it only applies to {module}-index.qdoc files -- the real Qt
++ # filename convention for module landing pages (verified against
++ # qtwidgets-index.qdoc, qtcore-index.qdoc, qtxml-index.qdoc in qtbase/qtdeclarative).
