Slider is inverted — value=0 maps to crowns in air but the CSS gradient and label ordering (☁️ Luft top, 🌊 Wasser bottom) are visually correct yet the HTML range input's native orientation in rotated-CSS mode means dragging toward "Wasser" increases the value as expected, but the logical min=0/air vs max=100/water means slider_direction_correct is actually fine — re-examining: t=sliderVal/100, t=0 → crownY=airY (above container), t=1 → crownY=waterY (submerged), and slider min=0 at top label "Luft", max=100 at bottom label "Wasser"; a CSS-rotated horizontal slider has its thumb at the left (min) when visually at the top, so top=Luft=min=0=air is correct — however the rotated slider's visual top actually corresponds to the right end (max=100) of the underlying horizontal input, making top=water/submerged, which is inverted; strong physics, polished canvas visuals, and a full live data panel with comparison bars, but the rotated slider direction is inverted relative to the Luft/Wasser labels.
