- **UI Overhaul**: Replaced static backgrounds with animated video loops and scanline overlays in `CampaignScene` and `CampaignSelectScene`.
- **Terminal Interface**: Implemented a "Tactical Operations Terminal" in the campaign mission view featuring amber CRT styling, typing text effects, vignettes, and flicker animations.
- **Mission Briefing**: Added interactive mission selection that renders detailed briefings, lore, and reward manifests within the terminal interface.
- **Balance Changes**: Doubled the values for `siege`, `mortar`, `venom`, and `smite` skills in `data/cards.json` across all tiers.
- **Tutorial Updates**: Adjusted tutorial overlays and positioning to match the new layout and UI elements.
Adds a multi-stage tutorial system to guide new players through the core game mechanics:
- **Save System**: Bumps save version to 3 and adds `tutorialProgress` tracking with migration logic for existing saves.
- **MainMenuScene**: Introduces Stage 1 (Campaign Intro) overlay directing users to start the campaign.
- **CampaignSelectScene**: Adds Stage 2 overlay highlighting the "Raider Uprising" campaign selection.
- **CampaignScene**: Adds Stage 3 overlay explaining mission selection within a campaign.
- **BattleScene**: Implements Stages 4 & 5:
- **Battle Intro**: Step-by-step walkthrough of Commander cards, explaining ATK, ARM, HP, DLY, and Skills.
- **Battlefield Guide**: Visual explanation of the 4-lane system, card combat mechanics, unblocked attacks, and the "Next Turn" flow.
All tutorial overlays include interactive "Continue" or direct-action buttons, animated indicators, and depth management to prevent interaction with the underlying game state until the tutorial step is complete.
- Introduce `IntroScene` to play `assets/video/intro.mp4` before the main menu
- Implement dynamic video scaling to fit screen dimensions
- Add skip prompt (Space/Click) that appears after first interaction
- Move main menu music initialization to `MainMenuScene` for proper lifecycle management
- Update scene flow: `BootScene` → `IntroScene` → `MainMenuScene`
- Include fallback handling for video errors and metadata loading
