+# sphinx-mcq
+
+Fresh SPHINX visual MC: charts, transformations and geometric counting.
+
+Uses four reviewed task families, native same-scene choices and nearby count
+alternatives. Original panel labels stay fixed in images. Gold comes from the
+native constructive generator and its uniqueness guards, not a model judge.
+Code is MIT; shipped icon assets carry CC BY 4.0 attribution.
