v2.0.0

Features

• Leaflet support: a third engine alongside MapLibre and OpenLayers — new LeafletAdapter({ map }) (a host-owned L.Map) + createLeafletMap, exported from the new @softwarity/sigmet-draw/leaflet subpath. Leaflet is an optional peerDependency (leaflet >= 1.9); 2D only (no globe, like OpenLayers). Load leaflet/dist/leaflet.css in the host.

Internal / API

• Shared adapter extracted to @softwarity/draw-adapter: the per-engine map adapters moved into a standalone, generic, data-driven package reused across the @softwarity drawing libs. sigmet-draw now consumes it through thin wrappers (MapLibreAdapter/OpenLayersAdapter/LeafletAdapter) that pre-bind the SIGMET layer manifest + hit set — construction is unchanged for hosts (new MapLibreAdapter({ map }) still works).
• Styling is now carried by the data: each overlay feature embeds its render props, baked from the resolved SigmetStyle by decorate() (style-features.ts), so the adapter never sees a domain type (the ~57 in-adapter SigmetStyle references are gone). Live setStyle(…) re-bakes and re-renders. No change to the public SigmetStyle shape.
• New exports: SIGMET_LAYERS, SIGMET_HIT, decorate. The toolbar / tooltip DOM helpers moved into the shared lib (src/map/toolbar.ts / tooltip.ts removed). adapter.ts is now a back-compat shim re-exporting the generic types under their historical names (OverlayId, Projection, MapAdapter, …).
• The OpenLayers DragPan/singleclick fix (1.1.2) and the icon-rotation conventions now live once in the shared lib and apply to all three engines.

Demo

• Engine switch is now three-way — MapLibre / OpenLayers / Leaflet.
