/* ---------------------------------------------------------------------------
   The working day, in one section.

   The headline makes the claim across the full width. Beneath it, on the left,
   the things the claim is about — a parking meter, a toll barrier, a receipt in
   a wallet, drawn in the site's own screen-print hand — then the three
   chapters of the film. On the right, the film itself: the same parking and
   toll turning up as £4.20 and £3.50 against the jobs they belonged to. Claim,
   objects, proof, in reading order, with nothing between the theatre and here.

   Two pieces of page rhythm.

   The journal ran a different pastel behind each illustration, which is the

   the difference. And the working-rhythm block arrives straight after the film
   at the same headline weight, so it competes with it — it is a coda to the
   demonstration, not another chapter, and it now reads at that rank.
