McKinsey-Style Market-Research Deck

Build a research-backed, visually elite, page-turning deck (HTML reviewed on screen → PDF for sharing). This skill is the distilled, reusable playbook. Read the four reference files as you reach each phase — do not try to hold all of it in head at once.

• references/methodology.md — how to do the research and what each section must contain
• references/design-system.md — the locked visual contract (tokens, page types, layout laws)
• ../mckinsey-deck/assets/deck_engine.py — the canonical engine (owned by the mckinsey-deck style skill; this skill consumes it — never fork a local copy, that's how drift starts)
• references/qc-checklist.md — the self-verify pass before delivery
• references/image-handoff.md — the template that hands product/cover images to an image generator
