   Concept: a samrap is not a list of dishes, it is a round tray with the
   curries set around the rice. So this site's organising shape is the circle,
   not the card grid — and the page is dark, because the restaurant only opens
   at night. Signature: the samrap ring (see .ring), used on the home page and
   the menu page and nowhere else.
