Installer corresponding source

The application source and its own BUILD script are in the parent directory.
This directory adds the exact installer script, artwork, guard C# source,
component notices and optional invitation flow used for the release.

To rebuild an unsigned installer on Windows:
1. Build the parent application using its supplied instructions.
2. Install Inno Setup 6.5.4 from the official upstream project.
3. Run PowerShell BUILD.ps1 -ApplicationDirectory <built app directory>
   -InnoCompiler <path to ISCC.exe> -OutputDirectory <output directory>.
The script recompiles the guard and recomputes the actual payload manifest.
It does not require the original build machine or publisher signing key.

Official main/Setup/guard/uninstaller signatures are applied separately by
the publisher. No signing credentials or private keys are included.
The reviewed optional RK invitation is obtained from its vendor at setup
time; it is not embedded in this archive or the application. Microsoft
WebView2, where required, retains Microsoft's original licence/signature.
It is a separately distributed prerequisite, not modified application code.

Installer integration and guard source follow the application's licence;
third-party components retain the individual licences supplied with them.
