+- `DocumentSource` now parses polygons with any number of points (three or more pairs) instead of requiring exactly four, and supports the page-only `D(page)` form. When only a page number is available, `getPolygon()` and `getBoundingBox()` return `null`.
+- Added `Sample_Advanced_ContentSource` and `Sample_Advanced_ContentSourceAsync` samples demonstrating how to read document grounding sources and render field highlight overlays.
