	// ========================================
	// Potential Future Improvements (Comment Block)
	// ========================================
	/*
	Potential Areas for Expansion/Improvement:

	* More Scene Variety: Add more create...Assembly functions and corresponding illustration keys for greater visual diversity (e.g., villages, ruins, different cave types, interiors).
	* More Complex Scenes: The current scenes are quite abstract. More detail could be added, potentially involving more complex geometry generation (e.g., procedural buildings, terrain algorithms) or even simple pre-made models loaded for key elements (like the statue, specific monsters).
	* Interaction: Add interaction with the 3D scene (e.g., clicking on objects using raycasting to examine them, pick up items visually, or activate levers).
	* Combat System: Implement a more detailed combat mechanic instead of abstract resolution (e.g., turn-based, display enemy models, track enemy HP, use stats for attack/damage rolls, visual feedback for hits/misses).
	* Character Progression: Implement a level-up system based on XP (increase stats, HP, unlock abilities/spells). Check for level up after gaining XP.
	* Save/Load: Add functionality to save and load game progress (perhaps using `localStorage` to store the `gameState` object as a JSON string). Add save/load buttons to the UI.
	* Data Management: For a larger game, storing `gameData` and `itemsData` in external JSON files and fetching them (`Workspace` API) would be more manageable than keeping them inline.
	* Error Handling: Add more robust checks for missing data (items, pages) or potential errors during scene generation and game logic. Improve feedback on errors (e.g., specific messages instead of just going to page 99).
	* Code Organization: Split the JavaScript into modules (e.g., `three-setup.js`, `game-logic.js`, `ui-manager.js`, `scene-generator.js`, `data.js`) for better maintainability using ES6 modules and imports.
	* Refine Scene Logic: Improve how scene elements correspond to game state (e.g., actually remove defeated goblin models from the scene, visually represent items found on the ground before pickup, change scene lighting based on time of day if implemented).
	* Add More Mechanics: Implement status effects (poison, bless), equipment slots (weapon, armor, shield) with stat modifiers, spells with costs (mana/charges), currency/shops, more complex skill checks (e.g., opposed checks, checks with advantage/disadvantage based on items/status), quest tracking system.
	* Accessibility: Review and improve accessibility (ARIA attributes for dynamic content updates, keyboard navigation for choices).
	* Performance: For very complex scenes or many objects, consider optimizing geometry (instancing similar objects like trees/rocks), using lower-poly models, texture atlases, and optimizing the render loop. Dispose of unused Three.js objects properly.
	* Sound/Music: Add background music loops and sound effects for actions, ambiance, and feedback.
