+Collections and projects now support avatar (thumbnail/icon) and banner (header/cover) images. Images can be provided as
+Blobs for upload or as URI strings for external references.
+
+**What's Included:**
+
+- Comprehensive JSDoc documentation for `HypercertCollection` type explaining avatar and banner usage
+- Tests for creating collections with avatar/banner using both Blobs and URI strings
+- Tests for updating collection images (add, update, remove, preserve)
+- Examples showing avatar/banner in collections and projects
