/* Vasco AI Assistant - floating task-oriented panel. Functional styling only for
   Phase A; the full glassmorphism/"Travel OS" visual treatment is a later phase -
   see docs' AI Assistant plan. Uses the existing design-system.css tokens so it
   doesn't introduce a second, inconsistent visual language in the meantime. */
