- Update `game.js` configuration to 1920x1080 with `Phaser.Scale.FIT` for responsive window resizing.
- Scale all UI elements across scenes (MainMenu, Battle, DeckBuilder, Collection, Store, Fusion) to match the new resolution:
- Increase font sizes by ~35-50% for better readability.
- Enlarge buttons and interactive areas to accommodate the larger viewport.
- Expand card display dimensions in battle and deck management screens.
- Adjust layout coordinates in `BattleScene` to center the 4-lane arena properly on the wider screen.
- Update `BootScene` loading text to center dynamically based on scale dimensions.
- Add project documentation (`CLAUDE.md`) outlining architecture, scene flow, and data models for future contributors.
