## Real-time / live updates
### Server-sent events for data changes
When data changes on the server (upload, edit, delete — from any client), connected
browsers should receive a notification and update the affected view automatically.
Use case: uploading photos from a phone while the desktop browser has the Images or
Bins section open.
Server-sent events (SSE) are the natural fit — lightweight, one-directional, no
library needed. The server emits a change event with a `type` (e.g. `source_images`,
`bins`) and the client re-fetches and re-renders only the affected collection.
Views that aren't currently visible don't need to do anything — they'll reload on
next navigation.
Ties directly into the delta tracking plan: the same write path that appends to the
delta log can also fan out to connected SSE clients.
