/* Agent Smith demo — the LINE-OA walkthrough on the /ralph page.
 * Uses the house tokens declared in wiki.css; adds no new colour, radius or font.
 * Mobile first: the frame is a single column that grows a side rail at 900px.
 * Sizing rule, same as the pool: every track is minmax(0, …) and nothing may
 * widen the page — the chat scrolls VERTICALLY only, and its bubbles wrap.
