Interactive cross-feature navigation architect for Nicolify. Audits all routes and sidebar entries, maps user journeys across studios, detects orphaned features and dead-end flows, proposes navigation improvements with ASCII diagrams, generates clickable multi-page HTML prototypes on localhost:8888, and outputs FLOW-SPEC.md plus per-screen UI-SPEC updates for implementation agents. Use when the user asks about navigation coherence, user flows, journey mapping, orphaned features, dead-end screens, sidebar reorganization, cross-studio navigation, or feature discoverability.
