   Digital OPD — public site
   ---------------------------------------------------------------------
   Direction notes, so the next person does not undo them by accident.

   Palette extends the product's own tokens rather than inventing a
   marketing identity. A doctor who sees the site and then the software
   should not feel handed to a different company. One colour is added:
   a muted sage for the chat thread in the hero, so the WhatsApp
   metaphor reads without impersonating WhatsApp's own green.

   No web fonts. The audience is a doctor on mobile data in a tier-2 or
   tier-3 town; first paint must not wait on a font CDN. The system
   stack is pushed hard on weight and tracking instead.

   The hero is the thesis: the message that starts a visit on the left,
   the printed prescription that ends it on the right. That pair is the
   one memorable element and everything around it stays quiet.
