# Notes

## Learner profile
- Frontend engineer; sibling tracks: SSE, Web Workers, IndexedDB, Cache API, OPFS, Service Workers (in progress or complete in this repo)
- **Motivation:** general FE toolkit depth — design-review judgment for browser platform APIs
- **Prior knowledge:** full track complete — spectrum, API/events, deal-breakers, decision playbook
- **Depth:** system-design decisions + interactive practice; light hands-on later if useful
- **Why this topic:** GitHub issue #5; fills the Web Storage / short-lived state gap after durable stores

## Teaching preferences
- Decision frameworks, tradeoffs, deal-breakers
- Browser APIs and integration difficulty from an FE perspective
- Short interactive lessons (same shape as other tracks)
- Cite high-trust sources; don’t invent API behavior
