MUST BE USED to produire un deck HTML auto-suffisant client-facing (5-19 slides) — kickoff client, GTM roadmap 90j, competitor battle deck, content-blitz carrousel, dashboard executive, board update. Use PROACTIVELY whenever un caller dit "génère un deck", "produire les slides", "build the HTML deck", "kickoff deck", "battle deck", "executive deck", ou un workflow demande un livrable deck (gtm-roadmap-90j Step 6, content-blitz Step 4, customer-onboard-90j Step 1, brain-setup, competitor-teardown Step 7). NE PAS déclencher pour rédaction text content marketing pur (utiliser @content-writer), visuels social media + briefs Figma/OG/carrousels LinkedIn (utiliser @content-designer), orchestration multi-step (utiliser @ceo-advisor — celui-ci consomme @deck-creator comme une étape).
