Mapbox GL JS — advanced web toolkit (v3)

An advanced toolkit for building production Mapbox GL JS map experiences on the web: markers, thematic dataviz, 3D, terrain, cinematic camera, style composition, performance, and the hard-won gotchas that bite. Scope: mapbox-gl-js v3.x in the browser (CDN mapbox-gl-js/v3.x/) — not the native iOS/Android SDKs (different APIs). Plain GL JS, framework-agnostic. Several patterns were distilled from a production trail map; adapt the constants to your own design.
