Web push uses one Declarative Web Push JSON payload carrying no PII (brand title, generic body, same-origin navigate path) so real content only loads after tap-through session auth, delivered synchronously and bypassing the outbox.
When to use: Use when adding browser push notifications that must render on iOS Safari without SW code while staying privacy-safe on lock screens.
