Replace hardcoded entity colors with D-033 relationship palette: Player=#e0e8ff, Npc=unknown teal #4a9ebb, Object=grey #8b8ba0. Phase 1 defaults by entity kind; Phase 2 (#361) will derive color from RelationshipState via knowledge graph. Entities in peripheral vision dimmed to 50% alpha (D-015). Player entity gets a Polygon2D triangle indicator showing facing direction, rotated from GameState.player_facing. 82 tests total, 0 failures. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
