CHANGELOG.md

 ## [Unreleased]
 
+### Fixed
+- UI elements (stockpile panel, controls hint) now reposition correctly after window resize
+- Centered overlay panels (build menu, villager panel) close on resize so they reopen at the correct position
+- Mouse world coordinates now use `ptr.worldX`/`ptr.worldY` in BuildingSystem and FarmingSystem, fixing misalignment after resize or zoom
+
 ### Added
 - Right-click context menu: suppresses browser default, shows Build and Folks actions in the game world
 - Initial project setup: Phaser 3 + TypeScript + Vite
