PWA Guideline

Tech Stack

• Framework: Next.js
• Platform: Vercel

Non-Negotiables

• Service worker must not cache personalized/sensitive/authorized content
• Cache invalidation on deploy must be correct (no stale content)

Context

A PWA is an opportunity to deliver native-like experience without an app store. But a bad PWA is worse than no PWA — stale content, broken offline states, and confusing installation prompts erode trust.

Consider: what would make users want to install this? What should work offline? How do we handle the transition between online and offline gracefully?
