 **`?from=card` query param**: Handlers check this to return different component variants for card vs detail page contexts (e.g., `UpdateList`, `DeleteList`, `ToggleItem`).
 
-**SSE events**: `event.Broker` publishes space-scoped events. Templates subscribe via `hx-sse="connect:/app/spaces/{id}/stream"` and trigger refreshes with `hx-trigger="sse:event_name"`.

 **CSRF**: Double-submit cookie pattern. Use `@csrf.Token()` in every form.
 
 **Auth flow**: JWT in HTTP-only cookies. Routes wrapped with `middleware.RequireAuth` and `middleware.RequireSpaceAccess` for space routes.
