 /**
  * The workspace the session points at, or null while nothing names one — nobody signed in, no
  * workspace selected, or a workspace row the device has not pulled yet. The three are one answer
  * here on purpose: a caller can only ever render "we cannot name it", and telling them apart would
  * be inventing a distinction no screen acts on.
  *
  * Read off [WorkspaceRepository.getAll] rather than the suspend `getById`, for the reason
  * [GetSpentMonthUseCase] observes a base currency the same way: a rename, or the pull that first
  * lands the row, has to reach the screen without something re-subscribing, and a one-shot read
  * latches whatever the device happened to hold at collection time.
