Slider direction is inverted (min=0 at top maps to crowns in air, but the label reads "LUFT ↑ WASSER ↓" suggesting bottom should be water — however the value mapping sets t=0 at top meaning crowns stay in air, which is correct directionally, yet the -webkit-appearance:slider-vertical on a bt-lr writing-mode typically renders bottom-to-top numerically, making the physical slider top=max=submerged and bottom=min=air, i.e. inverted); mass is static (not a live updating value element); ASCII-art rendering is creative but limited in spatial resolution for communicating water rise difference clearly.
