Fournissez des NotificationRow et acceptez activate, mark-read et dismiss-row par token et génération. Gardez le placement de la popup et les libellés mark-read-label et read-label stables pendant l’ouverture.
Le retrait bloque les actions puis émet la demande après un fondu de 150 ms, supprimé en mouvement réduit ; changer d’identité annule le retrait en attente. Les grandes collections utilisent une liste virtualisée et focus-token avec focus-request permet de retrouver un aperçu.
