/* ============================================================================
   TourismRevenue — AI assistant drawer (.ast-) and public visitor chat (.pcw-)
   Same tokens, radii and shadows as the ibjx copilot drawer; every colour is a
   design token from app.css so both themes and both palettes keep working.
   The two "on primary" colours are derived tokens: white surface in light mode,
   the light text colour in dark mode — never a literal.
