   header.css — app header bar, nav, avatar, and the profile dropdown menu.

   LOAD ORDER: after tokens.css, base.css, layout.css, components.css;
   before pages.css, legacy.css. The `header.nav` back-compat aliases for
   every selector below live in legacy.css instead (see that file); nothing
   in this file depends on legacy.css's load position since the paired
   rules carry identical declarations and legacy.css is only ever more, not
   less, specific.
