 * replaces with the place's path (app/dev/_door.tsx `moved`). The document moves
 * once, before anything is drawn or asked for; the id is carried as one

/**
 * The apex: the landing for a stranger, the web app for a signed-in reader.
 *
 * `/` is this site's search result and its share card, and every crawler that
 * reads them arrives as a stranger — so the export answers with the whole
 * landing and the metadata that describes it, byte for byte.
 *
 * A SIGNED-IN READER IS ANSWERED WITH THE APP (app/_web.tsx), in Chat; Dev is
 * the same app at `/dev`. It is the same address, not a trip somewhere else, so
 * a sign-in lands here, a reload stays here, and hanzo.ai typed by a member
 * opens their work. An old address, `/?chat=` or `/?at=`, moves to its path (`MOVED`). `Apex` decides in
 * the browser, because a static export has no server to decide with; `BOOT`
 * is the landing's first child and runs before the rest of it is parsed, so the
 * pitch never paints at a member while the app loads. An OAuth popup returning
 * here hands its answer to its opener and closes before any of it
 * (lib/auth/returned `RETURNED`).
