Fixed in https://github.com/badbundle/vault-app/pull/659 (merged as d9d27bcb).
Decision: the hint now starts empty. The question settled itself on these grounds:
- The field is labelled "Password Hint", and its footer called it "an optional hint … to help you remember its password". The old default wasn't a hint at all.
- The PDF already has a "Vault Export" title and says to open the Vault app and scan every code to import it, so the default text added nothing.
- Under C10, starting empty means a PDF prints nothing in plain text unless the user writes something.
Also changed:
- Making a PDF saves the hint, so any vault that made one without editing it had the old sample saved as its hint. That exact text is now treated as no hint.
- The footer now says the hint is printed in plain text, so anyone who sees the document can read it.
- Tests: new view-model tests, and the create-PDF snapshot is re-recorded.
