The core brain tracking player Elo and progression.
It manages the dynamic player HUD, displaying their current rank, next rank, and a smooth progress bar (complete with a "shadow bar" effect that feathers point gains/losses).
It handles all the complex math for ranking up or ranking down, triggering custom on-screen cinematics and sound effects when milestones are reached.
It oversees the prestige system, allowing players to reset their rank manually or automatically in exchange for a permanent prestige counter.
It securely links to the Persistence Manager to save the player's exact rank value, total eliminations, deaths, wins, losses, and current streaks between sessions.
