/* The site navigation, for every page that is not index.html.
 *
 * Copied from index.html's own nav so the two match, and put in a file because it had already
 * become three separate definitions of the same lockup — `.brand` in index.html, `.dnav .brand` in
 * docs.css, and a third in 404.html — which is exactly why imprint.html and success.html ended up
 * with no header at all. There was nothing to hand them.
 *
 * Two differences from index.html's nav, both forced by the fact that these pages are not it:
 *
 *   - Every section link is absolute (`/#formats`, not `#formats`). On these pages the sections
 *     are somewhere else, and a bare fragment under /docs/ or on a wrong path resolves to nothing.
 *   - No scroll-spy and no `.is-current` underline. Those mark which section of *this* page you are
 *     looking at, and here the answer is none of them. The links are exits, not a table of contents.
 *
 * Tokens are read with fallbacks: each page declares its own set, and they do not all match.
 *
 * index.html and the docs pages link this too and keep only what is theirs — index.html the
 * scroll-spy underline and its site-wide button, docs.css the `.dnav` bar the lockup sits in.
 * Both load it before their own <style>, so a local rule still wins where one is wanted.
