 * 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: THE CHAPTERS.
 *
 * NOTO SERIF DISPLAY OVER ASSISTANT: a high-contrast book serif for the
 * heads, the voice of a bound history, over a light, open sans for reading.
 * Plum on warm paper with a cream tint, and a near-black aubergine ink. The
 * plum (#7b2d5f) is 8.8:1 on white and 8.1:1 on the cream, so it carries
 * eyebrows and links; fills with white text use #5e1f48. On the aubergine of
 * the application band the eyebrow is a pale rose. The serif sets in a
 * lighter weight than the skeleton's default, the way a book's chapter
 * heads do.
