/* Two problems, one fix. (1) Labels of different lengths wrap to 1 or 2 lines,
   which otherwise leaves inputs in the same row starting at different Y
   positions - reserve a fixed height for every label (enough for 2 lines) and
   bottom-align the label text within it, so a 1-line label sits flush against
   its input exactly like a 2-line label's second line would, and every input
   in the form starts at the same offset regardless of its own label's length.
   (2) Different control types (a single input vs. a radio-button group) are
   different heights, which would otherwise leave inputs ending at different Y
   positions even with (1) solved - stretch each column to the row's full
   height and pin whatever follows the label (input, select, radio group,
   plaintext value) to the bottom, so every field's bottom edge - input,
   select, or otherwise - lines up on the same pixel across the row. */

     Top-aligned (not bottom): if a label's real rendered height ever exceeds
     this reservation by a hair in some browser's font metrics, the overflow
     spills below the box - into the already-flexible gap before the input -
     instead of spilling above it and inflating the row's own registered
