/* julianlupu.com -- dark, single frame per page.
   Advent Pro throughout, at three weights: 400 for prose, 500 for link labels,
   700 for the name and headings. Body text was previously 300 (Light), which is
   what made it hard to read -- the face is condensed, so it needs weight and a
   slightly larger size to hold up at paragraph scale.

   Indigo #5A56E0 (the color lipgloss uses) measures 3.77:1 on this background
   -- fine for large headings, short of AA for body text. Body-size indigo uses
   --indigo-text (#7B78F0, 5.68:1) instead. */
