Gamification & UI Modernization

[google-labs-jules]

This PR introduces a major UI overhaul and a new Gamification feature.

Key Changes:

1. UI Refresh:

   • Implemented a modern design system using Tailwind CSS v4.
   • Added full Dark Mode support with a persistent toggle.
   • Updated typography, shadows, and spacing for a professional look.

2. Gamification (Game Mode):

   • Created a new WelcomePage to choose between "Browse" and "Play".
   • Implemented GameLayout to handle game state (Random Start/Target Country selection).
   • Added game logic: Players must navigate from a Start Country to a Target Country using only border neighbors.
   • Added a "Win Condition" modal.

3. Routing:

   • Restructured routes to separate /browse (classic view) and /play (game view).
   • Refactored CountryPage to be reusable across both modes, adapting its UI (hiding back buttons/search in game mode).

Verification:

• Verified visually via Playwright screenshots (Dark Mode, Game Mode, Browse Mode).
• Lint checks passed.
