Regenerating a deck now costs credits

Regenerating a presentation now draws on your credit balance. It is not priced as a full deck: a regenerate skips research and section generation and re-renders content you have already paid for, so you are charged for the image generation alone — between 60 and 155 credits depending on the image source you pick. AI-generated imagery is the most expensive option and stock images the cheapest; the regenerate screen shows what each setting costs.

If your balance cannot cover it, the regenerate stops before it starts and no copy is created, so you are never left with a half-finished deck. The existing one-regenerate-per-deck limit is unchanged.
