/* Tokens — the one place the site's colours, type and spacing are decided.
   Linked from every page, ahead of that page's own <style> block, so a page
   only has to say what makes it different.

   The look is "herbarium": warm paper white, hairline rules, no rounded
   corners anywhere, and a lot of air. Two faces do all the work:

     Fraunces (serif)      titles and quotations, nothing else
     Source Sans 3 (sans)  everything else — body prose, facts, labels,
                           buttons, both map cards, the edit form

   Both are self-hosted from /fonts/, so the site still works offline. */
