/*
|------------------------------------------------------------------------------
| Kitchen display (§9)
|------------------------------------------------------------------------------
| The one screen in this system that is not read by somebody sitting down. It
| is on a wall, two metres away, in a room that is hot and bright, and it is
| glanced at by people whose hands are full. Everything below follows from
| that: dark, large type, four colours and no decoration.
|
| Dark regardless of the theme toggle. The rest of the admin follows whatever
| the operator picked; this does not, because a white board at this size in a
| dim kitchen at eleven at night is genuinely hard to look at - and the people
| reading it are not the people who set the theme.
