Build or extend a full topical map — a pillar/cluster/supporting content architecture grounded in entity-based semantic SEO — for a brand. Use whenever the user asks for a topical map, a content plan or content strategy, keyword clustering into topics, "what should we write about", niche coverage, or how to build topical authority — even if they only mention keywords or blog ideas. Produces topical-map.json plus a readable tree and a prioritised content calendar. If the brand has no entity-profile.json, run seo-brand-foundation first. Triggers on content-planning intent broadly, not just the literal phrase "topical map".
