Audit a python-pptx export against its source HTML deck, identify layout/content drift (footer overflow, cropped content, missing italic/em, lost styling, off-rhythm spacing), and re-export with strict footer-rail + cursor-flow layout discipline. Use this skill whenever the user has a .pptx that was generated from an HTML slide deck and asks to compare/audit/verify/fix the export — including phrases like "compare ppt with html", "fidelity audit", "fix the pptx", "ppt is cut off", "footer overlap", "italic missing in pptx", "re-export the deck", "pptx-html-fidelity-audit", or any case where a python-pptx → HTML round-trip needs verification or repair. Also trigger when the user shows you a deck.html and a deck.pptx side by side and is debugging visual differences.

# PPTX ↔ HTML Fidelity Audit
A repeatable workflow for catching the ways a `python-pptx` export silently drifts from its HTML source — and fixing them with a layout discipline that prevents the same regressions on the next pass.
## When this skill applies
The user has:
- A source HTML slide deck (typically a single-file deck with `<section class="slide">` blocks):
```html
<section class="slide light">
<div class="chrome">2026 · Q2 review</div>
<span class="kicker">Pillar 03</span>
