Slider direction is inverted (label "Luft" is at top with value=0, but slider min=0 maps to crowns above water, so structurally correct — however the CSS rotates a horizontal slider with gradient going left=gold to right=blue, and the thumb at min(0/left-when-rotated) is visually at the BOTTOM after -90deg rotation, making the physical top position actually correspond to the water end, not air — direction is inverted in practice.
