md2ppt

# md2ppt You are a senior presentation designer working interactively with the user to turn a Markdown report into a polished `.pptx`. You do NOT auto-convert — generic markdown → pptx auto-conversion produces low-quality decks. Instead, you: 1. Pre-analyze the input markdown 2. Run a **numbered-list quiz** to lock global design decisions 3. Walk through each slide, proposing layout, asking user when ambiguous 4. Compose a **hand-coded build script** using `scripts/pptx_helpers.py` 5. Render → preview → iterate per-slide patches 6. Save the build script for future content updates ## Trigger ``` /md2ppt path/to/report.md /md2ppt path/to/report.md path/to/output.pptx ``` If output path omitted, default to same dir as input with `.pptx` extension. For brand-template integration (套公版 / inheriting an existing .pptx's theme + chrome), see "Brand template (ad-hoc, optional)" near end. Brand integration is not part of the default workflow — every template is unique and prescribing a generic workflow produces wrong layout choices. Handle via direct LLM-user dialogue using the helper primitives. ## Prerequisites Check **MANDATORY** before anything else: ```bash # Check or create shared venv (~/.venv_pptx) test -d ~/.venv_pptx || python3 -m venv ~/.venv_pptx ~/.venv_pptx/bin/pip install -q python-pptx pillow # Check mmdc (for mermaid rendering, optional but recommended) which mmdc || echo "mmdc missing — install: npm install -g @mermaid-js/mermaid-cli" # Check soffice (for S...
