/* Subtle fade-up used for freshly-inserted content (simulation results,

   it doesn't just snap into view.
   Uses `top` instead of `transform` deliberately: any non-`none` transform
   (even an identity translateY(0)) creates a new CSS stacking context on the
   element, which trapped open .dsel-list dropdowns (z-index: 30) inside
   whichever .chain-row/.tp-row they opened from — a later row in the DOM
   (also a .reveal) would then paint its own opaque background on top of the
   earlier row's open dropdown, regardless of the dropdown's z-index. `top`
   on a `position: relative` box animates the same way without creating a
   stacking context, so z-index comparisons happen at the shared ancestor. */
