The deck wizard now shows what a deck really costs
The last step of the deck wizard used to say a deck would use "1 deck credit". That line was left over from before credits existed, and it was wrong: a deck is charged in credits, and the amount depends on what you configured.
The review step now shows the actual credit cost of the deck on screen, itemised: the fixed research part, the sections you selected, and the slides and images for the image style you chose. Two short lines underneath say what the same deck would cost with every section, and without images — so you can see which of your choices is moving the price. The figure is computed the same way the charge is, so what you see is what is taken.
Next to the cost is your balance and what will be left after this deck. If your balance does not cover the deck, the wizard now says so before you press "Create Pitch Deck" — with how many credits you are short and a link to add them — instead of failing after the click. Your settings are kept while you top up.
