Questions before we start.
Is a responsive website already a PWA?
No. Responsive layout adapts the interface; a PWA adds capabilities such as installation and a defined caching/offline strategy.
Can updates leave users on an old version?
They can. We design cache versioning and update prompts so an open session is not silently broken.
