+  Windows-natives Pendant zu bootstrap/neovim.sh - nutzt winget/npm statt
+  brew/pkg, daher eigenstaendiges Skript ohne Git-Bash-/WSL-Abhaengigkeit.
+
+  Aufruf (keine Admin-Rechte noetig):
+    .\bootstrap-win\neovim.ps1
+
+  yamlfmt, gawk und xmllint sind bewusst nicht enthalten (siehe
+  neovim-windows-setup.md). Fehlgeschlagene Installationen werden als
+  Warnung gemeldet, das Skript bricht nicht ab.
