// Rally geometry probe: `node tools/rally-sim.mjs` (RUNGS=1,6,12,18 SECS=240, CLASSIC=1 RUNGS=0,1,2 for
// the three classic difficulties). Plays the real modules headless with test.js's autopilot (auto-run,
// a fixed tap window, a random lane/deep flick) and prints WHERE each side meets the ball, how often
// it volleys, how long each shot gives the other side, and where rally balls land. It measures the
// shape of a rally, not a win rate — the bot is not Oliver. See PROJECT.md "THE RALLY GOES FLAT".
// ponytail: the platform stubs are copied from test.js; fold this into a test once the rework lands.
