LOCAL TWO-WINDOW TEST

1. Install Adofai See Together first.
2. Double-click "Start Two-Window Test.command".
3. Enter the main hub in both ADOFAI windows.
4. Confirm both windows say LOCAL PLAYER 1/2: Connected.
5. Move in one window. Only that player's remote pair should move in the other
   window, with its own rotation, colors, skin, particles, and trail.
6. Enter the same built-in level in both windows. Both labeled pairs should
   remain visible. Online/custom levels show portal presence only.

The remote balls never move by themselves. They display the actual positions,
sprite rotations, and appearance received from the other ADOFAI window through
localhost networking. The unfocused window continues updating during the test.

Close both windows normally when finished.
