   The paper layer: ako.ma on cream paper, inked in sepia, with painted
   headings. Loaded last, so it re-tints the design tokens (00_tokens.css)
   and dresses the shell (02_shell.css) without touching either; delete the
   <link> in index.html to go back.

   Paper is warm cream stock with a fine grain and soft, lighter blotches,
   like watercolour paper. The site is paper only: there is no dark theme.
