/*
  Styles for the server-rendered pages: /food/..., /list/... and /lists.

  Deliberately not the app's stylesheet. web/index.html carries about six
  hundred lines of CSS for a filter sidebar, a modal, a photo gallery and a
  paging control, none of which exists here. A crawler and a first-time visitor
  arriving from a search result both get a document that is a few kilobytes
  rather than ninety.

  The cost of that choice is a second copy of the design tokens below, and a
  second copy is how two things drift apart -- FOOD_GROUPS drifted from the
  classifier for a whole release behind a comment asking them to agree. So the
  tokens are checked rather than trusted: tests/verify_live.py reads --accent
  out of both files and fails if they differ.
