 ## [Unreleased]
 
+### Fixed
+- **Stockpile panel** (Issue #20): panel background now uses `uiOpacity` and updates live when Settings opacity changes; panel height increased so the Nisse count row no longer overlaps the carrot row
+- **ESC menu** (Issue #20): internal bottom padding corrected — last button now has 16px gap to panel edge instead of 0px
+
 ### Added
 - **Overlay Opacity Setting** (Issue #16): all UI overlay backgrounds (build menu, villager panel, context menu, ESC menu, confirm dialog, Nisse info panel, debug panel) now use a central `uiOpacity` value instead of hardcoded alphas
 - **Settings Screen**: ESC menu → Settings now opens a real overlay with an overlay-opacity row (− / value% / + step buttons, range 40 %–100 %, default 80 %); setting persisted in `localStorage` under `tg_ui_settings`, separate from game save so New Game does not wipe it
