/* Idle — a movement page for putting idle phones to work.
   The whole site is deliberately nocturnal: night is when a phone is charging,
   on wifi and free to work, and every illustration is set then. So there is one
   committed dark theme rather than a light/dark pair, and every colour is
   painted explicitly so nothing borrows the host background. */
