/* ===========================================================================
   Owlery Knits - one stylesheet.

   The hand: an undyed wool ground with navy ink, a brick red reserved for the
   active row and the live rail letter, and a moss green used only on figures.
   Everything is square. Tables are ruled like a workshop chart sheet - hairlines
   between rows, no fills, no shadows, no rounding. The single rounded shape in
   the file is the button, and it is rounded on the left only, the way a ball
   band sits on a skein.
