PLAY — Ranked Elo & Bot Ladder

Spec mockup for design/elo-ranking.md — the real FIDE Elo system (Rating Regulations effective 1 March 2024): K 40 for your first 30 games · K 20 under 2400 · K 10 permanently once 2400 is reached · rating difference capped at ±400 below 2650 · 0.5 rounds away from zero. Drag the rating slider or play rated games below; every region updates in place. Bot armies now field real cards: the tier's Legendary always carries ✦ AEGIS, and God tier is 25 gods (5 races × 5 elements) with a fixed retinue.
