Module game_tweens 

Game-specific tween presets — ready-to-call functions that wire the tween engine to specific game events: menu navigation, combat, screen transitions, stat changes, level ups, death, victory, and more.

Each function takes a &mut TweenManager and the minimum context needed (glyph IDs, bar IDs, positions, values), starts the relevant tweens, and returns the tween IDs for optional cancellation.
