Slider direction is inverted (min=0 at top maps to air, but `writing-mode: vertical-lr; direction: rtl` with no explicit label-to-behavior verification makes the thumb start at top=air correctly by accident via CSS inversion — however the labels say "☁️ Luft" at top and "🌊 Wasser" at bottom which matches, yet the crown moves DOWN as value increases which is correct — actually direction is correct); mass, volume, and density are static hard-coded values rather than live/dynamic displays, failing the live-value requirements for those three fields.
