   Periodic Table of Wine — site styles
   Tokens lifted verbatim from the original index.html so the grape pages and
   the table read as one object.

   Type note: Courier Prime is kept for tiles, labels and metadata — it is the
   brand voice. Long-form description copy uses a system serif stack instead:
   400 words of monospace is punishing to read, and nobody finishes it. No
   extra font is downloaded for this.
