   Dark-theme search affordance living in the navy #nav strip. Sole entry
   point for the cmd palette (the prior toolbar-mounted twin was removed -
   one global affordance avoids the "which search does which" confusion).
   `margin-left: auto` groups it with the right-side affordances (role
   context wrap) so it doesn't sit flush against the last chapter tab. */
