/**
 * Base class for all scenes. A scene is a `Container` (it owns a subtree of
 * display objects) plus four lifecycle hooks the SceneManager will call:
 *
 *   enter(data)              — called once after construction, before first render
 *   update(deltaSeconds)     — called every frame while active
 *   resize(width, height)    — called whenever the viewport changes (and once after enter)
 *   exit()                   — called once before the scene is removed and destroyed
 *
 * Scenes have full access to `game` (the PIXI app, systems, scene manager,
 * etc.) — see core/Game.ts for the surface area.
