 * On the ADR-0011 skeleton -- `tools/sitegen/page.css` is the layout. What is
 * here is the palette, the two typefaces, and the one band this site has
 * that the skeleton does not: DRAW YOUR LINES FIRST.
 *
 * BIG SHOULDERS DISPLAY OVER HEEBO, graphite on white with a cool grey
 * tint, and one deep cyan that marks every line. The cyan (#0e7490) is about
 * 5.4:1 on white, enough for eyebrows and links; fills carrying white text
 * use #155e75. Big Shoulders is a condensed face, so headings are set larger
 * and with a little air between the letters.
