+- `main()` implements the installed `dsh` console command and rejects an absent or blank `DSH_HOME`. On Windows it waits for the bundled process with inherited standard streams and forwards its exit status; on POSIX it replaces the Python process.
 
 Unsupported platforms and missing executables or sidecars raise `FileNotFoundError` with the build and installation routes. Unknown runtime modes raise `ValueError`.
