/* NOTE: we deliberately do NOT use viewport units (vh/dvh) for height. On the
   huggingface.co Space page the app runs in an auto-resizing iframe whose
   height tracks the content; vh-based heights create a feedback loop that
   blows the iframe up (and makes the outer page scroll forever). Instead the
   Chatbot gets a fixed pixel height (via its `height=` prop) and scrolls its
   message list internally, so the total app height is constant. */
