Agent Skills: strategy-memo

Create Amazon 6-pager-style data-backed strategy memos as Quarto documents (QMD → PDF). Use when asked to write a strategy pre-read, leadership memo, director briefing, executive narrative report, or any data-driven document following Amazon 6-pager conventions. Provides: an interview-then-scaffold workflow, a complete template QMD with caching/visualization/LaTeX patterns already wired, and supporting build tooling (Justfile, figure preview, cache validation). Auto-load when user says "strategy memo", "pre-read", "6-pager", "director briefing", "leadership document", "data-backed narrative", or "strategy document".
