+- The system allows players to toggle a free camera mode to photograph and collect museum items.
+- Game Pause: Activating the mode pauses the SceneTree, freezing the world while allowing the camera to remain functional.
+- Taking a photo saves the captured image to disk and checks which collectibles are visible and unobstructed before unlocking them.
+- CollectionManager acts as a global singleton that tracks unlocked collectibles, saved photos, and the data used by the UI.
+
+Photo Mode Actions:
+- Toggle Mode(P): Switches between normal gameplay and the photo camera, capturing or releasing the mouse, and toggles the global pause state.
+- Rotate(Mouse): The camera orbits around the configured target while photo mode is active.
+- Pan(Input Actions): The camera can be moved horizontally and vertically within the configured bounds.
+- Capture(F): Saves the current frame and performs frustum and raycast checks against collectibles in view.
+
+Core Components:
+- PhotoModeController: Manages camera inputs, movement logic, and the photo-taking process.
+- Collectible: An Area3D node placed on objects to make them identifiable by the camera.
+- CollectionManager: Handles the logic for unlocking items and provides data to the UI.
+- CollectibleGallery: Displays all collectibles and visually highlights the unlocked ones.
+- PhotoGallery: Displays the photos saved by the player during the session.
+
+Parameters:
+- Pan & Rotation Speed: Defines how fast the camera moves and rotates.
+- Movement Bounds: An AABB that restricts the camera's panning area.
+- Collectible Data: Resource files containing the ID, title, and image for each item.

+- The system is an extension of AudioStreamPlayer designed to manage sequential audio playback.
+- It automatically triggers the next track in the sequence when the current one finishes via the finished signal.
+
+Core Functionality:
+- Playlist Management: Stores a list of AudioStream resources and tracks the current song index.
+- Track Navigation: Allows cycling forward and backward through the playlist with index wrapping (loops back to start/end).
+- Playback Control: Supports jumping to specific tracks, toggling the pause state, and stopping the stream.
+- Audio Settings: If the Music bus exists, the Settings menu can be used to test and adjust playback volume.
+
+Key Methods:
+- play_track: Loads a specific stream from the playlist and begins playback.
+- next_track / prev_track: Increments or decrements the index to navigate the playlist.
+- toggle_pause: Resumes or pauses the current stream without resetting its position.
+
+Adjustable Parameters:
+- Playlist: An Array in the inspector where you can assign one or more AudioStream resources."
