All platforms; we already cache and serve locally using SQLite (see https://www.notion.com/blog/how-we-sped-up-notion-in-the-bro...) but the cache is built as an optimization -- loads look like `isFastDevice ? (await loadLocal(request) ?? await loadRemote(request)) : (race(loadLocal(request), loadRemote(request))`

We're working on redesigning the data architecture to be more truly "local first" where every read should come from local, and falling back to the server is a rare exception. We want this to look like `await loadLocal(request) ?? await sync({ priority: request }).then(() => loadLocal(request))`
