/** Imperative entry point — one call per Root transition.
    SURF-064/065: flushSync the `ag-src-<id>` name onto the source, then
    startMorph: inside the update the name leaves the source, update() is
    flushed, and only then is the destination resolved and named — so a
    Destination that mounts as a result of the update (list -> detail) gets
    the name for the new snapshot and receives focus. Lookups are scoped to
    `scope` (a Source click passes its SourceTransition.Root, so equal ids
    under another Root never collide; the static defaults to document). Focus
    moves only when the source contained document.activeElement at begin
    time. Both names are cleared when the morph settles. */
