If the user wants a brand match, load [`references/onboarding.md`](references/onboarding.md), propose the token mapping first, and write an approved project-local override under the injected `Visuals:` path. Apply that override to the current output and reuse it when the user asks for more diagrams in the same visual set.
Onboarding may read a public website, an installed skill, or a user-provided local design-token folder. It must not read credentials or private configuration, and it must not silently fetch or execute page scripts. If no brand source is provided, proceed with the defaults and state that choice briefly.
