feat: New GeoClipPath component for clipping content to GeoJSON boundaries in both SVG and Canvas modes (#449)
feat(Text): Add segments prop for inline mixed-style text (#449)

New segments prop accepts an array of { value, class } objects to render text with different styles (font size, weight, color) inline. Works across SVG (via tspans), Canvas (via sequential measureText/fillText), and HTML layers. Useful for labels that combine a bold name with a lighter value, such as treemap headers.
feat(Hull): Add CommonStyleProps (fill, fillOpacity, stroke, strokeOpacity, strokeWidth, opacity) for Canvas layer compatibility (#449)
feat(Tooltip): Add fadeDuration prop to control fade in/out transition (#828)

The fade transition on Tooltip.Root is now configurable via the fadeDuration prop (default: 100ms). Set to 0 to disable the fade transition entirely.
feat(Tooltip): Portal tooltip to body by default to fix overflow clipping. Resolves #446 (#828)

Tooltip.Root now portals to document.body (or .PortalTarget) by default using the portal action from @layerstack/svelte-actions. This prevents tooltips from being clipped by ancestor elements with overflow: hidden. The tooltip uses position: fixed with viewport-relative coordinates when portaled. Set portal={false} to restore the previous inline behavior. Both contained="container" and contained="window" modes continue to work correctly with portaling.

fix(ArcLabel): Support rotation in Canvas mode (#449)

Changed centroid-rotated and centroid-radial placements to pass rotate prop instead of SVG transform string to Text, enabling rotation in Canvas rendering.
fix: Pie and Arc components now correctly use Chart's xRange prop for angle degrees instead of the computed viewport pixel range, and compute radius from chart dimensions instead of scale range (#449)
