Feature Request: Big Screen Mode with animated draw for live events

[Spaccesi]

Summary

For conferences or events, a fullscreen presentation mode with a dramatic animated draw (e.g., spinning wheel, slot machine) would greatly enhance the audience experience.

Possible Solution

• Add a "Big Screen Mode" that goes fullscreen and hides UI chrome.
• On draw trigger, show a multi-second animation (wheel spin, drum roll, etc.) before revealing winners.
• Optimized for large displays / TV casting.

Acceptance Criteria

• A dedicated Big Screen Mode is accessible from the main screen.
• Draw animation lasts 3–7 seconds before revealing the winner.
• Mode is fullscreen and hides navigation elements.
• Works well on tablets and large screens.
