• Canvas API: Procedurally renders persistent neon nose-tracked fireworks strokes and the Clear All control on a full-screen transparent drawing surface.
• Sprite Store: Stores nine front-facing UI textures: seven neon color swatches plus active and paused drawing toggle states.
• FaceLandmarks: Tracks the user's 2D nose position every frame to drive the fireworks trail brush.
• Sprite Manager: Displays the seven palette swatches, draw/pause toggle, and Clear All control as a compact vertical group along the left edge, leaving generous open space above and below, with pixel-space hit testing for every control.
• Text On Screen: Shows the current drawing mode, selected color, and concise usage hints without covering the face.
• Touch Events: Captures taps for color selection, draw/pause toggling, and clearing the canvas.
