    // in a language, it ships an OCR model for that language. There is no interface language whose
    // text the app cannot read.

    // It drifted once already, because nothing checked: the UI shipped hu-HU while the catalog
    // stayed at eleven entries, and baobab-ts.com kept claiming OCR covered ten languages and that
    // Polish and Hungarian did not need models. OcrCatalogTests now reads Strings\*.xaml and fails
    // the build if these lists and that folder disagree, and release.ps1 runs the suite.
