   Paper
   The whole page is paper. Each section is a full-width sheet lying slightly
   over the one before it; sheets differ in tone and age:
     --white     fresh printer paper
     --offwhite  uncoated, slightly warmer stock
     --cream     heavier, creamy stock
     --aged      older paper with mottling
   Each paper type has its own subtle texture (img/paper-<type>.jpg, made by
   tools/make_texture.py): nearly white greyscale, multiplied onto the colour.
