Aggregates-only layer keyed by city_id (QuarterWorldState carries no spatial position — QuarterId is a content-addressed hash; a 512m quarter is sub-pixel at planetary projection, so no outline geometry by construction). Five quantized fields (density_avg_pct, dominant_district_type, dominant_zoning, landmark_count, corridor_count); scaled-glyph encoding anchored on the L3 settlement dot (shape=dominant type, color=density ramp); landmark/corridor counts tooltip-only per the D-226(d) aggregate-stats ceiling; five wiring touch points named for the follow-up ticket.
