Slides reworked after generation
Changing words keeps a slide editable. A slide you've reworked by hand or in chat comes through as one picture, because Pyntra builds the file from the deck's data and that slide no longer matches it. That covers an element moved, resized, added, deleted or recoloured, a swapped picture, changed chart text, and text long enough to shift the layout. The dialog lists these slides by number.
