Call it WITHOUT answers to get the questions to ask the user, then call it again with the budget and the answers. Read-only. Product names, verdicts and explanations are in French (French market). When nothing separates the finalists, the response says so (tied: true) and elects no winner: do not present any product as the winner in that case.
  - after: Returns the Pryx verdict (which product to buy) for one category, once the category's questions are answered. Call it WITHOUT answers to get the questions to ask the user, then call it again with the budget and the answers.

Product names, verdicts and explanations are in French (French market). When nothing separates the finalists, the response says so (tied: true) and elects no winner: do not present any product as the winner in that case.
