# Starting point: FE engineer, IDB for storage decisions

Learner is a frontend engineer with completed SSE and Web Workers missions in this repo. Goal is durable system-design judgment about client storage (when to use IndexedDB vs other browser stores), not shipping one offline feature. Treat Cache API / Service Workers as comparison points only until taught; do not assume schema-migration or multi-tab IDB experience. First ZPD lesson: place IndexedDB on the client-storage spectrum and practice choose/reject decisions.
