Function: isUuid()
isUuid(
id):boolean
Whether id is a UUID-shaped embed id. The marker grammar
(MARKER_RE) matches any non-bracket id token so fabricated
markers don’t leak as literal prose; this is the guard callers run
to decide whether an id is a real embed (render the slot) or a
bogus label to obscure (drop the marker entirely).
