This commit introduces a complete multi-page presentation system for the 20251012 event. Key features include: - **Page Structure:** Establishes the page flow with an entry point, a main cover scene, a committee list, and individual speech video pages. - **Real-time Chroma Key:** Implements a canvas-based green screen effect to composite a video onto a background image. A control panel allows for real-time adjustment of keying parameters, position, and scale. - **Unified Navigation:** A new `nav.js` script enables seamless navigation between pages using keyboard (arrow keys, Enter), touch swipes, and on-screen buttons. The navigation logic follows a predefined sequence (entry -> main -> committee -> speeches). - **Dynamic Content:** The committee list page dynamically generates its content from a JavaScript data source.
