"""Mantimon TCG - Core Game Engine.

This module contains the core game engine for Mantimon TCG, a highly configurable
Pokemon TCG-inspired card game. The engine supports both campaign mode with fixed
rules and free play mode with user-configurable rules.

Key Components:
    - config: RulesConfig and sub-configs for all game rules
    - models: Data models for cards, game state, and actions
    - effects: Effect handler system for card abilities and attacks
    - engine: Main GameEngine orchestrator
    - turn_manager: Turn/phase state machine
    - rules_validator: Action legality checking
    - win_conditions: Win/loss detection
    - visibility: Hidden information filtering for clients
    - rng: Random number generation with testable seeded implementation

Quick Start:
    from app.core import GameEngine, RulesConfig, create_rng

    # Create engine with rules and RNG
    engine = GameEngine(rules=RulesConfig(), rng=create_rng())

    # Create a game
    game = engine.create_game(
        player_ids=["player1", "player2"],
        decks={"player1": deck1, "player2": deck2},
        card_registry=registry,
    )

    # Execute actions
    result = await engine.execute_action(game, "player1", action)

    # Get client-safe view
    visible = engine.get_visible_state(game, "player1")
