## Summary
Azahar 2127.0 Alpha 3 is now available for testing. The release adds CSND module emulation, enabling audio for the 3DS keyboard applet, 3GX plugins, and early homebrew applications. It also fixes a Windows-specific hang when changing UI themes, improves input binding behavior with a confirmation dialog for conflicting hotkeys, and resolves a build failure with recent zstd versions.

## What's in this alpha
- **CSND module emulation**: Newly implemented, enables audio output for system applets (3DS keyboard), 3GX plugins, and early homebrew that relied on this sound interface
- **CIA installation fix**: Corrected handling of .zcia-compressed content within ROM bundles
- **Input binding UX**: Replaces silent failure with an explicit unbind confirmation dialog when hotkey conflicts occur
- **HLE GSP fixes**: Minor accuracy improvements that may resolve edge cases in certain games
- **Windows UI regression**: Fixed indefinite hang on theme change introduced in Alpha 1
- **Build system**: Resolved CMake target name conflict breaking compilation with newer zstd releases

## Why it matters
The CSND emulation fills a gap in homebrew and plugin compatibility, making Azahar more viable for users running non-commercial 3DS software. The zstd build fix helps downstream packagers on rolling distributions.
