Build a Brand Kit from a public website

Website analysis runs as a bounded background job. Public-address checks block local and private network targets before the worker fetches anything.

When extraction completes, the structured result is applied to the default brand and becomes available to writing, social, image, and chat context. Failed runs stay recoverable and never replace the current Brand Kit with partial output.

Teams managing separate products can add secondary brands from Brand Kit and keep each identity isolated inside the workspace.
