Competitive leaderboard

Ranked games require an authenticated account and a clock.

Ranked games use a server-selected color, a server-authoritative human clock, and a fixed deterministic node budget. Browser NPS is diagnostic only and never changes rating. Completed engine moves are reproduced by the server before a Glicko-2 result is accepted.
