/* ============================================================
   Support console — visual system

   Palette is the client's: deep forest for structure, sage for
   anything the bot did on its own, slate for anything a person
   touched, pale sage for washes. One colour sits outside that
   set — a muted clay for destructive actions — because a green
   "delete" reads as safe, and it must not.

   Colour carries state and nothing else. No decorative accents.
