/*
 * Shared site navigation.
 *
 * Every public page (landing, template gallery, login) renders the same bar,
 * in the same order, with the same labels. Previously each page hand-rolled its
 * own header, so the links visibly moved and renamed themselves as you browsed
 * — "Galeria de Exemplos" on one page was "Entrar no App" in the same slot on
 * the next.
