/*
 * docs.exointel.watch — the product's palette, at reading contrast.
 *
 * The app paints green-on-black because it sits over a map and never holds
 * more than a paragraph of text. Documentation is the opposite load, so the
 * accent stays for chrome, headings and links, and body copy runs at a plain
 * high-contrast neutral. The two look like the same product; only one of them
 * is legible for ten minutes at a time.
