+The test uses a disposable profile and Puppet daemon. It reads visible clues
+through snapshots, asks `puppet_choose`, then clicks and verifies feedback.
+It never reads the game's answer key. The first eight-round run scored 8/8:
+median choose time 264 ms, answer click plus verification 30.5 ms, combined
+292 ms. This small browser task does not measure native macOS use or prove a
+speedup over another model. Raw round results are in `wordplay/benchmark.json`.
