/**
 * The sections of the fofos admin, in nav order.
 *
 * ── The order is the client's site, not the database's ──
 *
 * It follows the sitemap: the pages someone edits most, first. Site settings, Messages and
 * Administration sit at the bottom because they are not pages — the site's settings, an inbox, and the
 * plugin's own machinery.
 *
 * ── `site` and `administration` are different things ──
 *
 * "Site settings" is the CLIENT's — partners, social links, contact details, all of it public copy that
 * whoever edits the site edits. "Administration" is OFFICER's end: where fofos is, how to reach it, and
 * whatever else this plugin needs to know to do its job. One is content, the other is plumbing, and the
 * people who touch them are not the same people. Nothing in Administration ever appears on the site.
 *
 * ── `built` ──
 *
 * The panels arrive one section at a time, each verified against the live site before the next is
 * started. A section that is not built yet says so, plainly, with what it will do — which is a better
 * answer than a nav that hides most of itself and gives no sense of what is coming.
 *
 * It mirrors `built` in fofos's own `src/apps/web/site-map.ts`, and for the same reason: one list, so
 * the nav and what actually renders cannot disagree.
