+
+          First Windows x64 desktop release. The installer is the recommended download.
+
+          **Recommended:** `SteamAPI-Desktop-Setup-v0.1.0-win-x64.exe` — standard Windows per-user installation with shortcuts and uninstaller.
+
+          **Alternative:** `SteamAPI-Desktop-v0.1.0-win-x64.zip` — portable version without installation.
+
+          Includes game search using the existing six-field SteamAPI backend contract, API Inspector, local companion API management, Settings, offline Demo Mode and About. The v0.2.0 backend API remains unchanged.
+
+          The installer is unsigned; Windows SmartScreen may show an Unknown Publisher warning. Compatible with Windows x64 and includes the .NET 10 runtime.
