  Prompt composer: autogrowing textarea, attachment chips, Enter-to-send and a send button that becomes Stop while streaming (the two lucide icons swap — not a true path morph, despite the description). Theme tokens. Pulls @smoothui/ai-core, imported by relative path (../ai-core), so keep both under components/smoothui/.
