/* streamlineai-chat-frontend/style.css — V1.4
 *
 * Cloned from frontend/style.css. Same black/gold/warm-white palette
 * (the StreamlineAI brand colours match what UPunt currently uses,
 * which makes sense since UPunt's frontend was built against the same
 * brand tokens). If StreamlineAI brand evolves later, fork the
 * --gold/--warm-white tokens here.
