Slider direction is inverted (label "WASSER" at top / "LUFT" at bottom, and value=0 maps to crowns in air while value=100 maps to crowns in water, but the rotated range input with `transform: rotate(-90deg)` means dragging the thumb upward increases the value, making the visual top correspond to "water" rather than "air").
