three-scope-map-skill

Build, migrate, theme, drill down, and validate reusable Three.js 3D geographic maps for Vue or web dashboards. Use when Codex is asked to create or modify province-level, all-China, or world 3D maps; switch map boundaries between provinces, country scope, world scope, city scope, or district scope; add hierarchical drilldown from world to country, China to province, province to city, city to district/county; replace GeoJSON, labels, scatter points, fly lines, terrain textures, or chase-light paths; derive a whole map color system from one theme color; or preserve an existing dark HUD-style 3D map visual across new regions.
