/*
 * Dispatch primary navigation.
 *
 * Shared header chrome for every admin page, including the older templates that
 * still carry their own page styles. Two rules shape this file:
 *
 *   1. Values are literal. It must stand alone on templates that never load
 *      /admin.css, so it cannot depend on that file's custom properties.
 *   2. Selectors use an element plus a class. A legacy template styles the same
 *      markup with single-class rules in a <style> block, and element+class
 *      outranks a lone class, so this file wins no matter which one loads last.
 *
 * Navigation is text only: no pills, no filled or outlined backgrounds. The
 * current page is marked with an underline.
