Recover editable PPTX from remark slide screenshots or exported pages

Hi, thanks for building remark.

One practical pain point with markdown/HTML slide workflows is that after slides are shared as screenshots, page images, or image-heavy PDFs, users lose actual editability in PowerPoint.

We are building slide-alchemy, an open-source workflow focused on converting picture-style slides back into editable PPTX with:

• real text boxes
• editable simple geometry when practical
• PNG assets for complex icons/decorations
• a clean regenerated base instead of reusing a full-slide screenshot

That seems relevant for remark users who want to recover an editable deck from the visual output of their slides.

Possible flow:

• remark screenshots / exported page images -> Slide Alchemy -> editable PPTX

If useful, I can follow up with a concrete integration sketch or sample results.
