Claude, I need your help implementing a critical game scene: PotionScene.

🔹 Context:

• This scene takes place after FujiForest and before Level1Scene.
• The player, currently the businessman, interacts with GameWizard (the shaman) in a pivotal moment where they must choose a potion to begin their Vision Quest.
• Upon selecting a potion, the businessman transforms into a corresponding traveler character for the rest of the game.

🔹 Game Functionality Required:

✅ Trigger Shaman Interaction

• When the player reaches a specific trigger zone, the GameWizard appears and delivers this dialogue:
  • "It is time to get the answers you seek. Select a potion to begin your Vision Quest."

✅ Potion Selection UI

• A popup interface should appear, displaying three potion choices:
  • 🟦 Ice Blue Potion → Transforms player into traveller2 (iceblue)
  • 🟥 Red Potion → Transforms player into traveller
  • 🟩 Green Potion → Transforms player into traveller1 (green)
• Potion assets: Located in assets/images/potions/
  • iceblue.png
  • red.png
  • green.png

✅ Implement Selection Logic

• When a player clicks a potion, store their selection in gameState and immediately update the player sprite accordingly:
  • traveller (red) → traveller-neutral.png, traveller-walk1.png, traveller-walk2.png, traveller-walk3.png
  • traveller1 (green) → traveller1-neutral.png, traveller1-walk1.png, traveller1-walk2.png, traveller1-walk3.png
  • traveller2 (iceblue) → traveller2-neutral.png, traveller2-walk1.png, traveller2-walk2.png, traveller2-walk3.png
• This new traveler sprite should persist across all future levels.

✅ Scene Transition to Level1

• After selecting a potion, the screen should fade to black, and when it fades back in, the businessman is now the chosen traveler and the player enters Level1Scene.

🔹 File Locations & Naming Conventions:

• Potions: assets/images/potions/
• GameWizard sprite: assets/images/shaman/GameWizard.png
• Businessman sprites: assets/images/characters/businessman/
