/* Afterchat landing page. One story in four steps (answers, keeps the answer, counts requests,
   your coding agent builds it), drawn once as a loop and then one section per step, one visual
   each. Tokens come from ../ui/tokens.css.
   Colour does the same jobs as in the app: green is live, new, up or done, red is "needs a
   person", both small and next to a word. Each visual has one focal point in full ink and the
   rest steps back to ink-2. Sections sit on stone, white bands separate them, and only the
   coding agent and the closing section are graphite. */
