/* Tim Phelps resume site. Engraved-letterhead look: deeper warm paper,
   rich navy ink, oxidized copper. Display type is Source Serif 4 (sturdy,
   conventional ampersands); text is its companion Source Sans 3.
   Hierarchy comes from the serif/sans contrast, weight, and letter-spacing,
   like a finely set printed letterhead. Layout and copy are frozen. */
