   Boulean Logic — site styles

   A Victorian treatise on bread, as reproduced in 2003 by someone with MS
   Paint and a free web host. Alegreya carries the titles and page copy,
   Alegreya Sans the post bodies, and Courier New anything that looks typed;
   web-default link colours, flat Paint-palette fills, 2px black borders and
   no rounded corners. Pictures are pixel art and must stay that way.
