- Export Signal type (signal → Signal) so subpackages can reference it - Expose viewport signals as public fields (CenterLng, CenterLat, Zoom, Bearing, Pitch) for .Text() display and .Bind() usage - Add signal-backed marker positions (LngSignal/LatSignal) with data-effect reactivity for server push and dragend writeback - Add event system (MapEvent, OnClick, OnLayerClick, OnMouseMove, OnContextMenu) using hidden inputs + action triggers - Add Source interface replacing type-switch, with RawSource escape hatch - Add CameraOptions for FlyTo/EaseTo/JumpTo/FitBounds/Stop - Add Control interface with NavigationControl, ScaleControl, GeolocateControl, FullscreenControl - Expand Options with interaction toggles, MaxBounds, and Extra map - Add effectspike example to validate data-effect with server-pushed signals - Update maplibre example to showcase all new features
