/* Site theme: the 96-well assay plate.
   Wells (circles with a thin rim) are the recurring motif: the homepage plate,
   card and tile markers, the current-page nav pill, and the portrait rims on
   /people. Red marks a "hit": the current page, hover, or a filled well.

   Loaded after each page's own <style> block, so rules here win ties with
   the page-level styles they restyle. */
