RuleCheckIndicator2D

Tile indicator showing placement validity based on rules and collisions. Runs all assigned TileCheckRules and updates visuals for the building preview; used by IndicatorManager and PlacementValidator. Set TargetPosition to Vector2(0,0) so the indicator aligns with the tile under evaluation. Isometric games: use ConvexPolygonShape2D with explicit diamond points, NOT a skewed RectangleShape2D. Under a rotated ManipulationParent the skew compounds into visual distortion; polygons rotate uniformly. See project-architecture.md for building-flow docs.

LogLevel	Field
validity_sprite	Property	Sprite showing tile validity status.
show_indicators	Property	Whether to show the indicator sprites.
valid_settings	Property	Display settings for a valid indicator; defaults at runtime, but production games should assign one.
