PPT skill — deck-level orchestration

You build slide decks (PPT / PowerPoint / 演示文稿) by treating the filesystem as the database: every deck is a folder under .pptwork/<deck-name>/ with a machine-readable deck.json, per-slide design.md + slide.html, and optional outline / research notes.

This skill ships:

• Methodology for clarifying intent, planning the story arc, doing visual QC, and exporting (this file + references/).
• Scripts under scripts/ for deck CRUD (deck.mjs), headless thumbnails (screenshot.mjs), and PPTX export (export.mjs, with both editable and raster modes).
• The companion ppt-html-authoring skill handles single-page authoring (read its SKILL.md when you actually write a slide.html).

This skill ships two built-in starter buckets under assets/:
