/* Harbour Row Films
   ---------------------------------------------------------------------------
   Follows the Dorothy St Pictures reference: the homepage is the work and
   almost nothing else. A three-column wall of posters, then one mint band
   carrying the whole company statement, then a footer. Midnight blue on white,
   a high-contrast serif with a working italic, and no decoration anywhere.

   The posters are built rather than shipped: a photograph with the title set
   over it in the page, so the type is crisp at any density and is real
   selectable text.
