; NSIS installer hooks for yurou
; Override file association DefaultIcon to use custom file icon (yurou-sys.png → file-icon.ico)

!macro NSIS_HOOK_POSTINSTALL
  ; Read the file class (ProgID) registered by Tauri's APP_ASSOCIATE,
  ; then overwrite its DefaultIcon to point to our custom file-icon.ico
  ; instead of the application exe icon.
  ;
  ; This repeats for every extension we registered.
  ; If the extension was not associated (backup value is empty) we skip it.
