   Folio: a printed book.

   Scene: a developer at a desk in daylight, coffee going cold, reading 1,500
   words properly. So: light, warm paper; one ink; a table of contents rather
   than a feed; a text column set like a good trade paperback.

   Color: restrained. Tinted paper, tinted ink, and vermilion used the way a
   printer uses a second colour: numbers, the initial, a rule, a link underline.
