 * Dark, high-contrast, and built around data rather than decoration. The

 * make "present" and "absent" instantly legible. Teal is held, amber is
 * missing, and those two colours mean the same thing on every chart, every
 * diagram and every terminal block on the site.
 *
 * No webfonts — they cost a render-blocking round trip and every platform
 * ships a good serif and a good mono.
