/* ==========================================================================
   Everett Altmann — plane spotting

   The whole design comes off the airfield itself. The page sits on Pacific
   Northwest overcast grey, the type is airport-signage condensed, and the one
   colour is the yellow used on taxiway guidance signs — the same yellow
   sitting in the corner of the photograph on the front page.

   The signature is the strip: every photograph is captioned the way an air
   traffic controller writes a flight progress strip, in fixed monospace
   columns — registration, type, operator, field. It's not decoration. It's
   exactly what a spotter writes down.
