- Updated `data/cards.json` to significantly increase armor values across all card tiers and types for better survivability balance.
- Refined skill descriptions in `data/skills.json` (Pierce, Berserk, Protect, Jam, Enfeeble) to clarify mechanics like "this turn" vs "permanent" effects and added flavor text.
- Added video background support to `MainMenuScene.js` using the new `tyrants-edge-menu.mp4` asset.
- Implemented retro VHS visual overlays on the menu: scanlines, stepped vignette, rolling tracking bar, and random screen flickers for atmospheric effect.
