Imported from /srv/add01/wow-ascension/Interface/AddOns/Bartender4 — the build Ascension's WotLK 3.3.5 client ships. Single vendored drop: Ascension's build process bundles their custom patches with the standard CurseForge packager output (embedded libs), and the individual patches aren't published separately. Net delta vs Nevcairiel 4.4.2, excluding bundled libs and CRLF normalization: 21 files, 2213+/52- — the Ascension-specific adaptations for WotLK 3.3.5 hero classes / custom action systems.
