/* The site's header and footer, in one place.
 *
 * These used to exist twice: the homepage had the design's navbar and a full footer, the
 * four generated sub-pages had a stripped bar and two lines of copy, and the two drifted
 * because nothing tied them together. This file is the single source for both, and it is
 * self-contained: styles.css is not loaded on the sub-pages, so every value the chrome
 * needs is either here or a var() with a literal fallback.
 *
 * Load order on the homepage is styles.css, then this, then home.css. Same specificity as
 * the legacy .navbar rules in styles.css means this wins on order, which is the intent.
