RNK Lobby is a system-agnostic module for Foundry VTT that allows Game Masters to place their world into a "GM Prep Mode" (formerly Maintenance Mode). When active, players are prevented from interacting with the game world and are instead presented with a customizable, full-screen lobby overlay. This is perfect for setting up scenes, preparing encounters, or taking a break without players wandering around.

• Secure Lobby Overlay: Blocks player access to the canvas, sidebar, and controls while the GM works.
• GM Control Center: A dedicated dashboard for the GM to manage the lobby state, chat, polls, and settings.
• Countdown Timers: Display a countdown to the start of the session or the end of a break.
• Live Chat & Monitoring: Chat with players directly from the lobby overlay. The GM can monitor player chat even while they are locked out.
• Interactive Polls: Run quick polls to gather player feedback or make decisions while they wait.
• Customizable Themes: Choose from built-in themes (Crimson Dawn, Midnight Vigil, etc.) or fully customize colors, fonts, and background images.
• Presets: Save and load your favorite lobby configurations.
• Analytics: Track session durations and engagement.

1. Copy the rnk-lobby folder to your Foundry VTT Data/modules/ directory.
2. Launch Foundry VTT and enable the module in your world's Manage Modules settings.

1. Log in as a Gamemaster.
2. Go to the Token Controls (left sidebar) and look for the RNK Lobby tool.
3. Click the Toggle GM Prep Lobby button.
4. Confirm the activation. All connected players will immediately see the lobby overlay.

Once the lobby is active, the GM will see a minimized control panel. Expand it to access:

• Status: View active players and lobby duration.
• Appearance: Change the background image, title, message, fonts, and colors.
• Countdown: Set a timer for when the game will resume.
• Polls: Create and manage polls for your players.
• Chat: Send announcements or chat with players in the lobby.

You can customize the look and feel of the lobby to match your campaign's aesthetic:

• Background: Upload your own image or use the default.
• Themes: Select from pre-configured themes like Crimson Dawn, Midnight Vigil, Verdant Harbor, or Emberfall.
• Fonts: Choose from a variety of Google Fonts for headings and body text.
• Blur & Opacity: Adjust the background blur and overlay opacity for readability.

• GM Preview Mode: Allows the GM to see the lobby overlay for testing purposes (configured in Module Settings).

RNK Lobby is system-agnostic and should work with any Foundry VTT game system (D&D 5e, Pathfinder, etc.).
