  - show_semi: Semi-transparent only when Shift/Ctrl are held down
  - semi_transparent: Fully visible when held, 40% opacity when not
- Added ↑↓ buttons in the Creative inventory panel to adjust page order (current page follows the movement)
- Added HUD scale options (auto/1/2/3/4) — HUD physical size remains unchanged when the screen scales
