Platforms

Platforms is where the PWA promise meets reality: the same manifest and service worker behave differently on iOS/WebKit, Chrome/Android, and the desktop. Install flows, available capabilities, storage durability, and notification support all vary by engine and surface — so shipping a great PWA means designing for each platform’s feature set, not the spec in the abstract.

These entries cover what works where, and the constraints to design around.
