   _visual-chat.css — Premium Chat Panel Visual Overhaul
   Kvill Mobile — "Гена" AI Assistant

   Dependencies: style.css (tokens), mobile.css (base chat layout)
   Loaded AFTER mobile.css — overrides chat section styles.

   ─── HTML CHANGES NEEDED ─────────────────────────────────────────────

   1. In .m-chat-panel, ADD an empty-state div inside #mChatMessages
      (shown when no messages exist, hidden when messages appear):

      <div class="m-chat-empty" id="mChatEmpty">
        <div class="m-chat-empty-avatar">
          <svg viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2"
               stroke-linecap="round" stroke-linejoin="round">
            <polygon points="13 2 3 14 12 14 11 22 21 10 12 10 13 2"/>
          </svg>
        </div>
        <div class="m-chat-empty-title">Гена</div>
        <div class="m-chat-empty-text">Скинь данные, Excel, PDF или опиши задачу — соберу презентацию</div>
        <div class="m-chat-empty-chips">
          <button class="m-chat-chip" data-prompt="Квартальный отчёт с KPI и графиками">Отчёт с KPI</button>
          <button class="m-chat-chip" data-prompt="Коммерческое предложение для клиента">КП для клиента</button>
          <button class="m-chat-chip" data-prompt="Питч-дек для инвесторов с метриками">Питч-дек</button>
        </div>
      </div>

   2. The .m-chat-close button currently uses class "m-chat-close" in HTML.
      CSS below targets both .m-chat-close and .m-chat-close-btn for compat.

   3. The textarea currently has class "m-composer-input" in HTML.
      CSS below targets both .m-composer-input and .m-chat-input.

   4. The send button has class "m-composer-send" in HTML.
      CSS below targets both .m-composer-send and .m-chat-send.

   5. "Гена" status indicator:
      <div class="m-chat-subtitle">
        <span class="m-chat-status-dot"></span>
        презентации из данных
      </div>
