   AI CLINIC DASHBOARD — Appearance Customizer
   Per-user colour picker panel (sidebar / background / accent …)

   The panel deliberately styles itself from its OWN tokens instead of
   the global --surface / --text variables: those are exactly the values
   the user is editing, so borrowing them would let a bad pick make the
   editor itself unreadable.
