/* 2. A two-line label ("Target concentration (mg/mL)") pushed its own input below its

   own 0.68rem size, so 2.5em fell short of two lines, and it wasted space on every
   single-line label anyway.

   Instead make each field a grid whose first row absorbs the slack. Grid items already
   stretch to the tallest field in the row, so pinning the label to the bottom of a 1fr
   row lines up every control — and costs nothing when all the labels are short. */

     Pinning line-height here makes 2.6em exactly two lines at any of the three sites'

     cannot share a row height, so the second row of a wrapping field set broke. */
