ng update @angular/material

Failed to process stylesheet: /src-tauri/target/release/build/app-14adf6121cc77f44/out/tauri-codegen-assets/02668f68735a10e28b660435a19e01a31eafb3a9b8e031639337b6bd71c0dec6.css (see error above).

IMO, instead of this structure:

/angular.json
/src-tauri
      ...

we should have:

/src-angular
     angular.json
     ...
/src-tauri
    ...
