Showcase arguments now show the text they came from

The curated arguments — Madison, Mill, Socrates — were published before the app could hold the original document alongside them, so they have been reading as arguments with no source. Each one now carries the canonical text it was built from, with the passage behind each claim highlighted in it. The Singer essay is the exception and stays as it is: it is still in copyright, so its text is not ours to publish.

Clearer wording when an argument falls short

The explanations shown after a review are rewritten in one voice. Three of them could not be resolved from the reader's side — one said to "withhold that one input" without saying which input, another left it unclear what "nothing here gets to it" referred to — and the two explanations about a conclusion the reader supplied no longer say the reader answered the conclusion itself, which was not true of a reader who had only answered part of it.
