   ASSESSMENT FEATURE  ·  v4
   The six-question diagnostic engine's editorial numbered-list UI
   (screens s1-s6). Identity preserved: a numeral, a label, a rule —
   no icon tiles, no bordered cards. v4 lights the canvas through,
   warms the selected row, and gives the progress bar a living gleam.
