Wraps Leaflet.js as native Web Components. Each element maps 1:1 to a Leaflet object with reactive attribute binding and proper lifecycle cleanup. Key design decisions: - LeafletElement base class handles attribute→option mapping, the leaflet-register bubble event for parent/child wiring, and disconnectedCallback cleanup tracking parent bindings. - LeafletControl base class for map controls (zoom, attribution, scale). - leaflet-map uses a PROPS table to drive observedAttributes, getters/setters, attributeChangedCallback, and map event listeners from a single source of truth. Property types are derived via a mapped type over the table; the mixin-base pattern (TypedBase) makes them visible to TypeScript without an interface merge. - Boolean map options that default to true use disable-* attributes. - Leaflet and its CSS are bundled into dist/index.js via esbuild. - JSR config included for @buddy/leaflet-components.
