/* ==========================================================================
   OneScreen — "Noticeboard"

   The product is a physical thing: a board in a room, and pieces of paper
   people pin to it. The interface is built from that, not from a dashboard.

   Paper and ink, not panels and glows. Hairline rules, not drop shadows.
   One accent — a vermilion that reads as a pin — and nothing else coloured
   except the work people send.

   Light is the default. Meeting rooms and classrooms have the lights on, and
   a dark screen in a lit room just looks like a grey smudge. The host can
   drop the lights for an evening or a dark auditorium.
