/* The documentation site's look.
 *
 * One accent colour that only ever means "this is a link or a control",
 * hairlines instead of boxes, and headings that separate sections on their
 * own. Teal is the project's colour, from the logo. Every colour is checked
 * against its own background, in both themes, at the 4.5:1 AA asks of text.
 * The dark theme is chosen, not derived: the same teal would be 2:1 there.
 * It is the one the site opens in, as the lab's other sites do.
 *
 * The four bases wear the report's palette, so a C on this page is the C of
 * the report. Those colours mark tiles, never letters: the letter stays in the
 * text colour, which is what keeps G legible on white.
