   WHO IT'S FOR — "The Interactive Accordion"
   Five tall glass pillars sit side-by-side. In the closed state,
   only a glowing icon is visible in each narrow column.
   On hover, the targeted pillar smoothly expands to reveal the text
   while all others compress — pure CSS flex mechanics, no JS needed.
