pptx-html-fidelity-audit

PPTX exports from HTML decks often drift from the source, causing footer overlaps, italic mismatches, and layout inconsistencies. A fidelity audit detects these drift patterns so the final PPTX faithfully mirrors the original HTML deck.

To verify python-pptx deck layout, use an extraction script to dump slide shapes and positions, then run a verification script to produce a deterministic audit table of issues with severity to drive fixes.

You can check footer rails and hero centering in exported PPTX files by applying cursor-flow discipline and explicit rail rules during a layout audit. This prevents content crossing rails and keeps hero slides properly centered.

Yes, python-pptx can be used to detect typography drift across multiple slides. An extraction script dumps typographic runs, enabling a fidelity audit to check font-slot consistency and italic preservation across the deck.

The best way to fix italic preservation and font-slot inconsistencies is to adjust export constants and font rules, then run a post-export verification script to confirm the layout matches the HTML source before final delivery.

You need a fidelity audit for PPTX files when exporting HTML slide decks to PPTX using python-pptx and noticing layout drift. It enforces deterministic checks and post-export verification to ensure the final output matches the source.
