Slider is inverted — value=0 maps to crowns in air and value=100 to submerged, but the CSS rotation trick means dragging the thumb upward increases the value, so the physical drag direction matches intent; however, the HTML min/max orientation is technically inverted from the spec (top=air is correct here but only incidentally via CSS transform), and the label "Ziehen zum Eintauchen" (pull down to submerge) conflicts with the rotated control's actual top-to-bottom drag behavior.
