   Concept: patients here are not only afraid of the drill, they are afraid of
   the bill. What the clinic sells is transparency, so the visual system is built
   from a ruler, not from tooth icons and rounded blue cards. Teal and mint —
   the default palette of every dental site — are deliberately absent; the ground
   is warm porcelain and the accent is coral. Mint appears in exactly one role:
   marking what social security covers.

   Signature: the price bar (.bar). Every service sits on the same 0–50,000 THB
   scale so two services can be compared by eye. A price that overruns the scale
   is cut with a zigzag and labelled with the real number — the scale is never
   squeezed to make something fit.
