/* ---- 19b. Before / after contrast --------------------------------------------- */
/*
   Laid out after `@/components/ui/compare-2` (kept for reference): two columns,
   the second one tinted from its heading to the foot of the list, each item a
   round mark beside a line of copy.

   Three departures, all forced by what this section actually says:

   1. **The rows stay paired.** The source is two independent lists — nothing on
      the left corresponds to anything on the right. Here every "before" maps to
      exactly one "after"; that mapping is the section's whole argument, so each
      pair shares a grid row and the two columns read across as well as down.
   2. **The left column is not ticked.** The source ticks both columns, because
      both are lists of things it is recommending. This left column is the state
      the reader is leaving — a tick beside "a scanner export with three hundred
      findings and no owner" would read as endorsing it. It gets a neutral rule
      instead, and only the right column is marked in accent.
   3. **The tint runs continuously.** The source paints its whole right-hand
      panel. Rows here are separate elements, so the tint is carried on each
      right cell with no row gap between them, which reads as one column.
