fix(lan-client): swap P3/P4 grid positions for clockwise turn order

Swapped CSS grid-area, zone-row anchoring, commander-row anchoring,
label corners, and life-panel positions for .p3/.p4 so the turn
sequence P1→P2→P3→P4 reads clockwise around the battlefield.
Also added PLAYER_INDEX_TO_QUADRANT lookup in player-panels.js.

-## Quick Start (Windows)
+---
 
-**Prerequisites:** Java 17+, Python 3.10+, Maven 3.8+, [Forge](https://github.com/Card-Forge/forge) built at `D:\ForgeCommander\forge-repo`
+## Features
+
+### Simulation Engines
+
+| Engine | Description | Speed |
+|---|---|---|
+| **Forge** | Rules-complete Java engine — handles the stack, instants, triggered abilities, and all Commander rules. Each game spawns a JVM subprocess. | ~0.04 sims/sec (single-threaded) |
+| **Monte Carlo** | Headless Python engine — models combat keywords (flying, trample, deathtouch, lifelink, menace, reach, haste), summoning sickness, tapped state, commander zone, multiplayer targeting, and board wipes. No JVM required. | Thousands of games in minutes |
+
+Both engines feed structured results into the same ML pipeline.
+
+### Deck Builder
+
+The `POST /api/deck-builder/build` endpoint runs a 7-step pipeline:
+
+1. Resolve commander via Scryfall
+2. Fetch EDHrec recommendations
+3. Fetch Scryfall candidates by category (ramp, removal, draw, lands)
+4. Ollama suggests synergy/protection/wincon cards — **simulation insights injected here**
+5. Filter by color identity, collection, and ban list
+6. Ollama enforces ratios (trim/expand to 99) — **simulation insights injected here**
+7. Assemble final deck with smart substitution (guarantees 99-card output)
+
+### AI Coach
+
+LLM-powered coaching with two modes:
+
+- **Full Session** — Deep analysis including removal coverage, ramp quality, draw engine profiling, win conditions, anti-synergy detection, pod meta evaluation, and tempo assessment
+- **Quick Digest** — Fast ~5-second summary for rapid feedback
+
+Coaching prompts are enriched with semantically relevant cards from the ChromaDB RAG store (15 cards for full sessions, 8 for quick digests). Supports both Anthropic Claude and local Ollama models with streaming responses.
+
+### RAG Card Knowledge
+
+- **SQLite FTS5** bulk card database from Scryfall data
+- **ChromaDB** vector index with natural-language card embeddings
+- Automatic staleness monitoring (checks every 6 hours, auto-rebuilds if >14 days old)
+- Graceful fallback — RAG failures never block coaching or deck building
+
+### ML Training Pipeline
+
+```
+Overnight sims → decisions_*.jsonl
+       ↓
+update_weights.py → learned_weights.json (feeds deck builder)
+       ↓
+/api/ml/train → neural net training on decision dataset
+       ↓
+/api/policy/decide → ML policy serves AI decisions in live games
+```
+
+- **Outcome-weighted RL** nudges card scoring weights from game results
+- **Neural net** trains on the full decision log dataset
+- **Distillation loop** — self-play → collect data → retrain → repeat
+- **ELO tracking** and model tournaments for comparing AI versions
+- Weights clamped to `[-20.0, 20.0]`, stored in `learned_weights.json`
+
+### Win Condition Tracking
+
+Games are classified by win type — not just "Combat" vs "Other":
+
+- **Combat** — standard creature damage wins
+- **Combo** — Approach of the Second Sun, Felidar Sovereign, Happily Ever After, and 30+ known alternate-win cards
+- **Drain** — life drain effects
+- **Mill** — library depletion
+- **Poison** — infect/poison counter wins
+
+Draw games (timeout) are analyzed separately with per-player life-at-timeout snapshots and likely cause identification.
+
+### LAN Battlefield Client
+
+Browser-based 4-player Commander game at `/lan`:
+
+- **AI Bridge** — REST + WebSocket connectivity with ML policy decisions as Priority 1 (falls back to local heuristic AI)
+- **Deck System** — 3-tab selector: Precons (163 decks, grouped by set), EDHREC search, and custom deck import
+- **Player Panels** — Life counters, commander damage bars, poison/energy/experience/rad counters, emblem management
+- **Backend Detection** — Auto-detects the Commander AI Lab backend; works offline with local precon data
+
+### Unity Client
+
+Full Unity application (URP, .NET Standard 2.1) with:
+
+- **Battleground Scene** — 4-seat layout with rotated perspectives, life/poison/commander damage widgets, phase tracker, turn order bar
+- **Card System** — Hand, battlefield, graveyard, exile zones with card art, tapped rotation, face-down state, summoning sickness indicators
+- **Stack & Mana** — LIFO stack display and 6-pip mana pool
+- **Lobby System** — Configure 4 seats (human/AI), POST to backend, WebSocket game state sync
+- **Elimination** — Grayscale shader overlay on eliminated players
+- **Token System** — Create, tap, add counters, delete tokens
+- **Cross-Platform** — Windows, WebGL, Android, iOS build targets
+- **Scenes** — MainMenu, Collection, DeckBuilder, DeckGenerator, Simulator, Coach, Scanner, Training, Precon, Battleground
+
+### Card Scanner
+
+OCR pipeline for physical Magic cards using the Ximilar API. Scan cards from photos and match them to the Scryfall database.

 ## Known Limitations
 
-- **Monte Carlo engine** — no stack, no instants, no continuous type changes (animated lands don't attack)
-- **Forge engine** — each game spawns a new JVM (~2-3s overhead), ~0.04 sims/sec single-threaded
-- **Forge winner life total** not captured (quiet mode only reports losers)
-- **Deck builder** — Ollama suggestions are only as good as the local model; `qwen2.5:7b` works well

+- **Deck builder** — Ollama suggestions depend on the local model quality; `qwen2.5:7b` works well
+- **LAN client** — EDHREC commander search is a stub (backend-powered, not yet fully wired)

+/**
+ * PolicyControllerAi — Phase 2 live-game controller that routes AI decisions
+ * through the Python policy server instead of Forge's built-in heuristics.
+ *
+ * <h2>Architecture</h2>
+ * <pre>
+ *   Forge game loop
+ *       └─ player.getController()            → PolicyControllerAi
+ *               └─ brains (PolicyAiController extends AiController)
+ *                       └─ chooseSpellAbilityToPlay()
+ *                               ├─ buildGameStateJson()
+ *                               ├─ policyClient.decide(stateJson)   → macro-action
+ *                               ├─ mapMacroActionToSpellAbility()   → SpellAbility
+ *                               └─ super.chooseSpellAbilityToPlay() (fallback)
+ * </pre>
+ *
+ * <h2>Two-class design</h2>
+ * <ul>
+ *   <li>{@link PolicyAiController} — inner subclass of {@link AiController}
+ *       that overrides {@code chooseSpellAbilityToPlay()}.  This is the
+ *       intercept point closest to the game loop.</li>
+ *   <li>{@link PolicyControllerAi} — subclass of {@link PlayerControllerAi}
+ *       that swaps Forge's default {@code AiController} for a
+ *       {@code PolicyAiController} and exposes lifecycle helpers
+ *       (game-end reward submission, statistics).</li>
+ * </ul>
+ *
+ * <h2>Decision flow</h2>
+ * <ol>
+ *   <li>Build a rich {@link JsonObject} snapshot of the current game state
+ *       (per-player life/mana/zones, stack, phase, legal actions).</li>
+ *   <li>POST the snapshot to {@code /api/policy/decide} via
+ *       {@link PolicyClient#decide(JsonObject)}.</li>
+ *   <li>Translate the returned macro-action name (e.g. {@code "cast_creature"})
+ *       to a concrete {@link SpellAbility} from the legal action list using
+ *       {@link MacroActionExecutor}'s card-role databases.</li>
+ *   <li>If the server is unreachable or no mapping succeeds, fall back to
+ *       {@link AiController#chooseSpellAbilityToPlay()} transparently.</li>
+ *   <li>Log every decision (policy or fallback) for training data collection.</li>
+ * </ol>
+ *
+ * <h2>Fallback guarantee</h2>
+ * Every code path in {@link PolicyAiController#chooseSpellAbilityToPlay()}
+ * is wrapped in a broad {@code try/catch}.  Any unexpected exception causes
+ * an immediate delegate to the parent Forge AI so the game continues safely.
+ *
+ * <h2>Usage</h2>
+ * <pre>{@code
+ * PolicyClient client = new PolicyClient("http://localhost:8080");
+ * client.connect();
+ *
+ * // When Forge constructs the AI player's controller:
+ * PolicyControllerAi controller = new PolicyControllerAi(game, player, lobbyPlayer, client);
+ *
+ * // After the game ends:
+ * controller.onGameEnd(won ? 1.0 : -1.0);
+ * }</pre>
+ *
+ * @see PolicyClient
+ * @see PolicyAiController
+ * @see MacroActionExecutor
+ * @since Phase 2.1 — Issue #83
