/* Fido Intake — AI interview chat surface
   ---------------------------------------------------------------------------
   Light, warm, editorial. Paper and ink, one cyan accent taken from the
   fidodesign.net brand colour. No dark surfaces, no glass, no glow.

   Palette tokens live on the intake wrapper (assets/intake.css); every use
   here carries a literal fallback so this file also stands alone.

   Contract IDs styled: #fi-chat #fi-chat-log #fi-chat-status #fi-chat-form
   #fi-chat-input #fi-chat-send #fi-chat-done #fi-chat-progress-text
