Generate IBM Consulting–branded interfaces, decks, landing pages, and prototypes using IBM's Carbon Design System conventions and the IBM Plex type family. Trigger on: "IBM Consulting deck", "IBM branding", "Carbon design", "IBM Plex", "IBM blue", BoxBoat/Nordcloud co-brand assets, or any throwaway mock/prototype/marketing page that must look like IBM Consulting materials. Do NOT use for: real IBM.com or product-UI production work (use `@carbon/react` + `@carbon/icons-react` directly — see Deferred below), or any deliverable presented as official/authoritative IBM guidance rather than an internal presentation aid.
