Wireframes - Data engine (W13–W19)

Low-fidelity layout wireframes: structure, hierarchy, and component placement - not visual design. Surface ownership: W1, W2, W6–W11, W14–W16 are Phoenix LiveView; W3, W4, and W13 (map canvas) are React islands; W5 and W12 are React Native / mobile web.

Each screen has its own page - pick one from the navigation to view the wireframe and leave comments.
