- Drop dead pgx.ErrNoRows guard in ABSBookmarkStore.Delete (Pool.Exec never returns it; the prior guard was misleading dead code). - Reject ±Infinity in parseBookmarkTime so a DELETE /…/bookmark/Inf URL path is consistent with the POST/PATCH body path (which JSON itself excludes — JSON has no Infinity literal).
