/*
  Opisometer website, laid out like the layout-template design: a near-black canvas,
  or a pale paper in the light theme, ruled with faint vertical guidelines; thin
  uppercase Google Sans headlines; small monospaced index labels; hairline panels;
  and one warm bronze accent for what you can act on.

  Google Sans Flex comes from Google Fonts for the thin weights; Google Sans itself
  starts at 400. The theme follows the device until the switcher in the header picks
  one (theme.js). On the About page, gallery.js opens a screenshot larger.
