/**
 * The panel docked in the page itself, for standalone hosts that serve the
 * panel from the page's own server (`createLitDevtools()`).
 *
 * A button in the corner opens a drawer along the bottom of the page with the
 * panel in an iframe. Framed by the page, the panel also reaches it over the
 * direct in-page channel (see `panel/in-page.ts`), so hovering the tree
 * highlights without a round trip to the server.
 *
 * Plain DOM in an open shadow root rather than a Lit element: the runtime
 * counts the page's Lit elements, and the dock is not one of the page's.
 * The iframe is only created on first open, so a dock nobody opens costs
 * the page nothing but the button.
 *
 * In a frame (a cloud IDE's preview) devframe cannot prompt for the one-time
 * code, so the dock asks for it: the button carries a dot, and the drawer
 * holds a field for the code instead of the panel until the server trusts the
 * page. The panel then loads with the token the page stored.
 *
 * A full page load takes the panel with it. The dock keeps what it can
 * across one: open or not, its height, and the panel's tab, read off the
 * panel's hash as the page goes. Not the selection: its ids name elements
 * of the page that is leaving, and on the next one could name others.
